RISK FACTORS

You should carefully consider the risks described below, in addition to the matters set forth under ‘‘Safe Harbor Statement under the Private Securities Litigation Reform Act of 1995’’ above, before making an investment decision. Our business, prospects, financial condition or operating results could be materially adversely affected by any of these risks, as well as other risks not currently known to us or that we currently deem immaterial. In assessing the risks described below, you should also refer to the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus, including our consolidated financial statements and the related notes and Item 1A, ‘‘Risk Factors,’’ of our Annual Report on Form 10-K for the year ended December 31, 2007, and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2008, in each case filed with the Commission, which are incorporated by reference herein (Incorporated Risk Factors), before deciding to purchase any Series C Notes. The factors described below must be read in conjunction with the Incorporated Risk Factors and are qualified in their entirety by reference thereto.

The infrastructure of our transmission and distribution system may not operate as expected, and could require additional unplanned expense which could adversely affect our earnings.

Our ability to manage operational risk with respect to our transmission and distribution systems is critical to the financial performance of our business.  Our transmission and distribution businesses face several operational risks, including the breakdown or failure of or damage to equipment or processes (especially due to age), accidents and labor disputes.  The costs (both labor and material) that our regulated companies incur to construct and maintain their electric delivery systems have increased in recent years. These increases have been driven primarily by higher demand for commodities and electrical products, as well as increased demand for skilled labor. A significant percentage of our regulated company equipment is nearing or at the end of its life cycle, such as old and obsolete distribution poles, underground primary cables and substation switchgear. The failure of our transmission and distributions systems to operate as planned may result in increased capital investments, reduced earnings or unplanned increases in expenses, including higher maintenance costs. Any such costs which may not be recoverable from our ratepayers would have an adverse effect on our earnings.

Changes in regulatory or legislative policy, difficulties in obtaining siting, design or other approvals, global demand for critical resources, or environmental or other concerns, or construction of new generation may delay completion of or displace our transmission projects or adversely affect our ability to recover our investments or result in lower than expected rates of return.

The successful implementation of our transmission construction plans is subject to the risk that new legislation, regulations or judicial or regulatory interpretations of applicable law or regulations could impact our ability to meet our construction schedule and/or require us to incur additional expenses and may adversely affect our ability to achieve forecast levels of revenues.  In addition, difficulties in obtaining required approvals for construction, or increased cost of and difficulty in obtaining critical resources as a result of global or domestic demand for such resources could cause delays in our construction schedule and may adversely affect our ability to achieve forecasted earnings.

The regulatory approval process for our planned transmission projects encompasses an extensive permitting, design and technical approval process.  Various factors could result in increased cost estimates and delayed construction.  These include environmental and community concerns and design and siting issues.  Recoverability of all such investments in rates may be subject to prudence review at the FERC at the time such projects are placed in service.  While we believe that all such expenses have been and will be prudently incurred, we cannot predict the outcome of future reviews should they occur.

In addition, to the extent that new generation facilities are proposed or built to address the region’s energy needs, the need for our planned transmission projects may be delayed or displaced, which could result in reduced transmission capital investments, reduced earnings, and limit future growth prospects.

The currently planned transmission projects are expected to help alleviate identified reliability issues and to help reduce customers’ costs. However, if, due to further regulatory or other delays, the projected

S-4





Table of Contents

in-service date for one or more of these projects is delayed, there may be increased risk of failures in the existing electricity transmission system and supply interruptions or blackouts may occur which could have an adverse effect on our earnings.  

The FERC has followed a policy of providing incentives designed to encourage the construction of new transmission facilities, including higher returns on equity and allowing facilities under construction to be placed in rate base before completion.  Our projected earnings and growth could be adversely affected were FERC to reduce these incentives in the future below the level presently anticipated.

Increases in electric and gas prices and focus on conservation and self-generation by customers and changes in legislative and regulatory policy may adversely impact our business.

The nation’s economy has been affected by significant increases in energy prices, particularly fossil fuels. The impact of these increases has led to increased electricity and natural gas prices for our customers, which has increased the focus on conservation, energy efficiency and self-generation on the part of customers and on legislative and regulatory policies.  This focus on conservation, energy efficiency and self-generation may result in a decline in electricity and gas sales in our service territories.  If any such declines were to occur without corresponding adjustments in rates, then our revenues would be reduced and our future growth prospects would be limited.

In addition, Connecticut, New Hampshire and Massachusetts have each announced policies aimed at increased energy efficiency and conservation.  In connection with such policies, all three states have opened proceedings to investigate revenue decoupling as a mechanism to align the interests of customers and utilities relative to conservation. In Connecticut, the Department of Public Utility Control (DPUC) authorized decoupling via a rate design that is intended to recover proportionately greater distribution revenue through the fixed Customer and Demand charges, and proportionately less distribution revenue through the per kWh charges. At this time it is uncertain what mechanisms will ultimately be adopted by New Hampshire and Massachusetts and what impact these decoupling mechanisms will have on our companies.

Changes in regulatory policy may adversely affect our transmission franchise rights or facilitate competition for construction of large-scale transmission projects, which could adversely affect our earnings.

We have undertaken a substantial transmission capital investment program and expect to invest approximately $3 billion in regulated electric transmission infrastructure from 2008 through 2012.

Although our public utility subsidiaries have exclusive franchise rights for transmission facilities in our service area, the demand for improved transmission reliability could result in changes in federal or state regulatory or legislative policy that could cause us to lose the exclusivity of our franchises or allow other companies to compete with us for transmission construction opportunities.  Such a change in policy could result in reduced transmission capital investments, reduce earnings, and limit future growth prospects.

Changes in regulatory and/or legislative policy could negatively impact regional transmission cost allocation rules.

The existing New England Transmission tariff allocates the costs of transmission investment that provide regional benefits to all customers in New England.  As new investment in regional transmission infrastructure occurs in any one state, there is a sharing of these regional costs across all of New England.  This regional cost allocation is contractually agreed to remain in place until 2010 by the Transmission Operations Agreement signed by all of the New England transmission owning utilities but can be changed with the approval of a majority of the transmission owning utilities thereafter.  After 2010, certain changes to the terms of the Transmission Operations Agreement could have adverse effects on our distribution companies’ local rates.  We are working to retain the existing regional cost allocation treatment but cannot predict the actions of the states or utilities in the region.

Table of Contents

Changes in regulatory or legislative policy could jeopardize our full recovery of costs incurred by our distribution companies.

Under state law, our utility companies are entitled to charge rates that are sufficient to allow them an opportunity to recover their reasonable operating and capital costs, to attract needed capital and maintain their financial integrity, while also protecting relevant public interests.  Each of these companies prepares and submits periodic rate filings with their respective state regulatory commissions for review and approval.  There is no assurance that these state commissions will approve the recovery of all costs prudently incurred by our regulated companies, such as for operation and maintenance, construction, as well as a return on investment on their respective regulated assets.  Increases in these costs, coupled with increases in fuel and energy prices could lead to consumer or regulatory resistance to the timely recovery of such prudently incurred costs, thereby adversely affecting our cash flows and results of operations.

In addition, CL&P and WMECO procure energy for a substantial portion of their customers via requests for proposal on an annual, semi-annual or quarterly basis.  CL&P and WMECO receive approvals of recovery of these contract prices from the DPUC and the Massachusetts Department of Utilities, respectively.  While both regulatory agencies have consistently approved solicitation processes, results and recovery of costs, management cannot predict the outcome of future solicitation efforts or the regulatory proceedings related thereto.  

The energy requirements for PSNH are currently met primarily through PSNH’s generation resources or fixed-price forward purchase contracts.  PSNH’s remaining energy needs are met primarily through spot market or bilateral energy purchases.  Unplanned forced outages of its generating plants could increase the level of energy purchases needed by PSNH and therefore increase the market risk associated with procuring the necessary amount of energy to meet requirements.  PSNH recovers these costs through its default energy service rate, subject to a prudence review by the New Hampshire Public Utilities Commission.  We cannot predict the outcome of future regulatory proceedings related to recovery of these costs.  

The loss of key personnel or the inability to hire and retain qualified employees could have an adverse effect on our business, financial condition and results of operations.

Our operations depend on the continued efforts of our employees.  Retaining key employees and maintaining the ability to attract new employees are important to both our operational and financial performance.  We cannot guarantee that any member of our management or any key employee at the NU parent or subsidiary level will continue to serve in any capacity for any particular period of time.  In addition, a significant portion of our workforce, including many workers with specialized skills maintaining and servicing the electrical infrastructure, will be eligible to retire over the next five to ten years.  Such highly skilled individuals cannot be quickly replaced due to the technically complex work they perform. We are developing strategic workforce plans to identify key functions and proactively implement plans to assure a ready and qualified workforce, but cannot predict the impact of these plans on our ability to hire and retain key employees.

Grid disturbances, severe weather, or acts of war or terrorism could negatively impact our business.

Because our generation and transmission systems are part of an interconnected regional grid, we face the risk of possible loss of business continuity due to a disruption or black-out caused by an event (severe storm, generator or transmission facility outage, or terrorist action) on an interconnected system or the actions of another utility.  In addition, we are subject to the risk that acts of war or terrorism could negatively impact the operation of our system.  Any such disruption could result in a significant decrease in revenues and significant additional costs to repair assets, which could have a material adverse impact on our financial condition and results of operations.

Severe weather, such as ice and snow storms, hurricanes and other natural disasters, may cause outages and property damage which may require us to incur additional costs that are generally not insured and that may not be recoverable from customers.  The cost of repairing damage to our operating subsidiaries’ facilities and the potential disruption of their operations due to storms, natural disasters or

S-6





Table of Contents

other catastrophic events could be substantial.  The effect of the failure of our facilities to operate as planned would be particularly burdensome during a peak demand period, such as during the hot summer months.  

A negative change in our credit ratings could require us to post cash collateral and affect our ability to obtain financing.

Our senior unsecured debt ratings by Moody’s Investors Service, Standard & Poor’s, Inc. and Fitch Ratings are currently Baa2, BBB− and BBB, respectively, with stable outlooks.  Were any of these ratings to decline to non-investment grade level, Select Energy, one of our remaining competitive businesses, could be asked to provide, as of March 31, 2008, collateral or letters of credit in the amount of $32.1 million to unaffiliated counterparties and collateral or letters of credit in the amount of $20.9 million to several independent system operators and unaffiliated local distribution companies (LDCs) under agreements largely guaranteed by us.  While our credit facilities are sufficient in amounts that would be adequate to meet cash calls at that level, our ability to meet any future cash calls would depend on our liquidity and access to bank lines and the capital markets at such time.

We expect to obtain the liquidity needed for our capital programs through bank borrowings, the issuance of long-term debt by our subsidiaries and debt and equity financing by us.  While we are reasonably confident these funds will be available on a timely basis and on reasonable terms, failure to obtain such financing could constrain our ability to finance regulated capital projects.  In addition, any ratings downgrade of our securities or those of our subsidiaries, or any negative impacts on the credit market, generally, could negatively impact the cost or availability of capital.

Changes in wholesale electric sales could require Select Energy to acquire or sell additional electricity on unfavorable terms.

Select Energy’s remaining wholesale sales contracts provide electricity to full requirements customers, including a regulated LDC and a municipal electric company.  Select Energy provides a portion of the customer’s electricity requirements.  The volumes sold under these contracts vary based on the usage of the underlying retail electric customers, and usage is dependent upon factors outside of Select Energy’s control, such as economic activity and weather.  The varying sales volumes may differ from the supply volumes that Select Energy expected to utilize from electricity purchase contracts.  Differences between actual sales volumes and supply volumes may require Select Energy to purchase additional electricity or sell excess electricity, both of which are subject to market conditions which change due to weather, plant availability, transmission congestion, and input fuel costs.  The purchase of additional electricity at high prices or sale of excess electricity at low prices could negatively impact Select Energy’s cost to serve the contracts.

We are subject to litigation which could result in large cash judgments against us.

We are currently engaged in litigation and may also be subject to future litigation based on asserted or unasserted claims and cannot predict the outcome of any of these proceedings.  Adverse outcomes in existing or future litigation could result in the imposition of substantial cash damage awards against us.

Costs of compliance with environmental regulations may increase and have an adverse effect on our business and results of operations.

Our subsidiaries’ operations are subject to extensive federal, state and local environmental statutes, rules and regulations which regulate, among other things, air emissions, water discharges and the management of hazardous and solid waste.  In particular, more stringent regulations of carbon dioxide and mercury emissions have been proposed in the various New England states in which we operate. Compliance with these requirements requires us to incur significant costs relating to environmental monitoring, installation of pollution control equipment, emission fees, maintenance and upgrading of facilities, remediation and permitting.  The costs of compliance with existing legal requirements or legal requirements not yet adopted may increase in the future.  An increase in such costs, unless promptly recovered, could have an adverse impact on our business and results of operations, financial position and cash flows.   

S-7





Table of Contents

In addition, global climate change issues have received an increased focus on the federal and state government levels which could potentially lead to additional rules and regulations that impact how we operate our business, both in terms of the power plants we own and operate as well as general utility operations.  Although we would expect that any costs of these rules and regulations would be recovered from ratepayers, the impact of these rules and regulations on energy use by ratepayers and the ultimate impact on our business would be dependent upon the specific rules and regulations adopted and cannot be determined at this time.

Any failure by us to comply with environmental laws and regulations, even if due to factors beyond our control, or reinterpretations of existing requirements, could also increase costs.  Existing environmental laws and regulations may be revised or new laws and regulations seeking to protect the environment may be adopted or become applicable to us.  Revised or additional laws could result in significant additional expense and operating restrictions on our facilities or increased compliance costs which may not be fully recoverable in distribution company rates for generation.  The cost impact of any such legislation would be dependent upon the specific requirements adopted and cannot be determined at this time.  

An active trading market for the Series C Notes may not develop.

The Series C Notes are a new issue of securities with no established trading market, and we do not intend to list them on any securities exchange. In addition, there may be little or no secondary market for the Series C Notes. Even if a secondary market for the Series C Notes develops, the liquidity of the secondary market, and the market price quoted for the Series C Notes, may be adversely affected by changes in the overall market for fixed income securities and by changes in our financial performance or prospects or the prospects for companies in our industry generally. In addition, any market-making activity by the underwriters will be subject to limits imposed by the Securities Act of 1933, and the Exchange Act. As a result, an active trading market for the Series C Notes may not develop. If no active trading market develops, you may not be able to resell your Series C Notes at their fair market value or at all.

USE OF PROCEEDS

We estimate that the net proceeds from the sale of the Series C Notes after payment of underwriting discounts and commissions and our expenses will be approximately $         million. We will use the net proceeds of the offering (i) to repay short-term debt, some of which was incurred to repay at maturity our $150 million Senior Notes, Series B, Due 2008, and (ii) for other general corporate purposes. As of March 31, 2008, we had approximately $145 million of short-term debt outstanding under our revolving credit facility, which had a weighted average annual interest rate of 3.573%.

DESCRIPTION OF THE SERIES C NOTES

The Series C Notes are a separate series of the Senior Notes described in the accompanying prospectus and will be issued under the Third Supplemental Indenture, dated as of June 1, 2008, between us and The Bank of New York Trust Company, N.A. (as successor trustee to The Bank of New York), as trustee, supplementing our Indenture with The Bank of New York Trust Company, N.A. (as successor trustee to The Bank of New York) dated as of April 1, 2002 (the Senior Note Indenture), described in the accompanying prospectus. You should read the accompanying prospectus for a detailed summary of additional provisions of the Senior Notes, including the Series C Notes, and of the Senior Note Indenture. The description of the Series C Notes below supplements the description of the Senior Notes contained in the accompanying prospectus. If the descriptions are inconsistent, this prospectus supplement controls. The following summary and the description set forth in the accompanying prospectus do not purport to be complete and are subject to, and qualified in their entirety by, all provisions of the Senior Note Indenture. Capitalized terms used but not defined in this prospectus supplement have the meanings given to them in the accompanying prospectus.

General

The Series C Notes will constitute the third series of our Senior Notes issued under our Senior Note Indenture. Our Senior Notes, Series A, Due 2012, in the aggregate principal amount of $263,000,000, constituted the first series of Senior Notes issued under our Senior Note Indenture and were issued April 1, 2002, and our Senior Notes, Series B, Due 2008, in the aggregate principal amount of $150,000,000, which were issued on June 2, 2003 and repaid on June 2, 2008, constituted the second series of Senior Notes under our Senior Note Indenture.

The Series C Notes are initially being offered in the aggregate principal amount of $    . We may, without the consent of the holders of the Series C Notes, create and issue additional notes ranking equally with the Series C Notes in all respects, including having the same CUSIP number, so that such additional notes shall be consolidated and form a single series with the Series C Notes and shall have the same terms as to status, redemption or otherwise as the Series C Notes, except for the date of original issuance, the initial interest payment date and the offering price. No additional notes may be issued if an Event of Default has occurred and is continuing with respect to the Series C Notes. The Series C Notes will mature on June 1, 2013. The Series C Notes are not entitled to the benefit of any sinking fund. The Senior Note Indenture permits the defeasance of the Senior Notes upon satisfaction of the conditions described under ‘‘Description of Securities Registered—Northeast Utilities—Senior Notes—Defeasance’’ in the accompanying prospectus and ‘‘—Defeasance’’ below.

The Series C Notes will be our senior unsecured obligations and will rank equally in right of payment with all our other unsecured and unsubordinated indebtedness, which at March 31, 2008 was $413 million, consisting of long-term debt and short-term debt. Because we are a holding company that conducts all of our operations through our subsidiaries, our ability to meet our obligations under the Series C Notes is dependent on the earnings and cash flows of those subsidiaries and the ability of those subsidiaries to pay dividends to us, repurchase shares of their common stock from us or repay loans or advances made by us to them. Dividends payable by certain of our subsidiaries are restricted pursuant to the terms of the subsidiaries’ long-term debt agreements and regulatory requirements, but we do not believe these restrictions should interfere with the payment of interest on or repayment of the Series C Notes. Holders of the Series C Notes will generally have a junior position to claims of any holders of preferred stock and creditors of our subsidiaries, including trade creditors, debtholders, secured creditors, taxing authorities and guarantee holders. In addition to trade debt, our subsidiaries have ongoing corporate debt programs used to finance their business activities. As of March 31, 2008, our subsidiaries had approximately $3.2 billion of outstanding external debt for borrowed money, which includes long-term debt (including $4.3 million due within one year) and short-term debt, but does not include trade debt, capital leases, power purchase obligations, liability for prior period spent nuclear fuel disposal costs, $856.3 million of rate reduction bonds, and $116.2 million of outstanding preferred stock. The Senior Note Indenture does not currently limit the amount of indebtedness or preferred stock we may issue. Please refer to ‘‘Description of Securities Registered—Northeast Utilities—The Senior Notes—General’’ in the accompanying prospectus.

Table of Contents

We will issue the Series C Notes in fully registered form in denominations of $1,000 and multiples thereof. The Bank of New York Trust Company, N.A., the Trustee under the Senior Note Indenture, will register transfers and exchanges of the Series C Notes and will serve as paying agent for the Series C Notes. Principal on the Series C Notes will be payable at the Trustee’s Corporate Trust Office which, at the date hereof, is located at 222 Berkeley Street, 2nd Fl., Boston, MA. 02116, Attn: Corporate Trust Administration. We will initially issue the Series C Notes in global form. Please refer to ‘‘—Global Securities’’ in this prospectus supplement and ‘‘Book-Entry System’’ in the accompanying prospectus.

Interest

The Series C Notes will bear interest at     % per year. We will pay interest semiannually in arrears on June 1 and December 1 of each year (each, an Interest Payment Date), beginning December 1, 2008, and ending on the maturity date. Interest on the Series C Notes will be computed on the basis of a 360-day year of twelve 30-day months and, for any period shorter than a full month, on the basis of the actual number of days elapsed in such period. If an Interest Payment Date or the maturity date of the Series C Notes falls on a day that is not a business day, the payment of principal and interest will be made on the next succeeding business day (without any interest or other payment in respect of such delay).

Interest on the Series C Notes will accrue from, and including, the date of original issuance of the Series C Notes to, and excluding, the first Interest Payment Date and then from, and including, the immediately preceding Interest Payment Date to which interest has been paid or duly provided for to, but excluding, the next Interest Payment Date or the maturity date, as the case may be. In addition, interest and principal which is overdue shall bear interest at the rate of    % per annum.

We will pay the interest due on any Interest Payment Date to the person in whose name the Series C Note is registered at the close of business (1) on the business day prior to each Interest Payment Date if the Series C Note remains in book-entry only form or (2) on the fifteenth calendar day before each Interest Payment Date if the Series C Note does not remain in book-entry only form.

When we use the term ‘‘business day,’’ we mean any day except a Saturday, a Sunday or a legal holiday in the City of New York on which banking institutions are authorized or required by law, regulation or executive order to close.

Optional Redemption

The Series C Notes may be redeemed in whole at any time or in part from time to time at our option at a redemption price equal to the greater of:

  one hundred percent (100%) of the principal amount of the Series C Notes being redeemed, plus accrued interest thereon to the redemption date; or   as determined by the Quotation Agent, the sum of the present value of the remaining scheduled payments of principal and interest on the Series C Notes to be redeemed (not including any portion of payments of interest accrued as of the redemption date) discounted to the redemption date on a semi-annual basis at the Adjusted Treasury Rate plus        (    ) basis points, plus accrued interest to the redemption date.

The redemption price will be calculated assuming a 360-day year consisting of twelve 30-day months.

‘‘Adjusted Treasury Rate’’ means, with respect to any redemption date, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that redemption date.

‘‘Comparable Treasury Issue’’ means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the Series C Notes that would be used, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Series C Notes.

‘‘Comparable Treasury Price’’ means, with respect to any redemption date: (i) the average of the Reference Treasury Dealer Quotations for that redemption date, after excluding the highest and lowest

S-12





Table of Contents

of the Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than three Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations so received.

‘‘Quotation Agent’’ means the Reference Treasury Dealer appointed by us.

‘‘Reference Treasury Dealer’’ means a primary U.S. Government securities dealer in New York City selected by us.

‘‘Reference Treasury Dealer Quotations’’ means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by that Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding that redemption date.

If less than all of the Series C Notes are to be redeemed, the Trustee will select the Series C Notes to be redeemed by a method that the Trustee deems fair and appropriate and which may provide for the selection for the redemption of portions (equal to $1,000 or any multiple thereof) of the principal amount of the Series C Notes larger than $1,000. Notice of redemption will be mailed, first-class mail postage prepaid, to each holder of Series C Notes to be redeemed at the holder’s address in the register for the Series C Notes. If any Series C Note is to be redeemed in part only, the notice of redemption that relates to that Series C Note will state the portion of the principal amount of that Series C Note to be redeemed. In that case, we will issue a new Series C Note of any authorized denomination, as requested, in an aggregate principal amount equal to the unredeemed portion of such Series C Note, in the name of the holder upon cancellation of the original Series C Note.

We will mail notice of any redemption, not more than sixty (60) days nor less than thirty (30) days before the redemption date (which notice may be made subject to the deposit of redemption moneys with the Trustee or any paying agent before the redemption date), which, so long as the Series C Notes are held in the book-entry only system, will be DTC, its nominee or a successor depositary. Any notice of redemption may state that such redemption shall be conditional upon the receipt by the Trustee or any paying agent, on or prior to the date fixed for such redemption, of money sufficient to pay the principal of, and premium, if any, and interest, if any, on such Series C Notes to be redeemed on such date and that if such money shall not have been so received such notice shall be of no force or effect and we will not be required to redeem such Series C Notes.

Unless we default in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Series C Notes called for redemption.

Limitation on Liens and Sale and Leaseback Transactions

The covenants set forth in the accompanying prospectus under ‘‘Description of Securities Registered—Northeast Utilities—The Senior Notes—Limitation on Liens’’ and ‘‘—Sale and Leaseback Transactions’’ have been made applicable to the Series C Notes.

Defeasance

We may defease the indebtedness on the Series C Notes on the terms described under ‘‘Description of Securities Registered—Northeast Utilities—The Senior Notes—Defeasance,’’ in the accompanying prospectus. In addition, we may defease the Series C Notes within 60 days prior to maturity without delivering an opinion that the defeasance will not cause the holders of the Series C Notes to recognize income, gain, loss or expense for Federal income tax purposes. The purpose of this provision is to give us more flexibility in timing a refinancing of the indebtedness represented by the Series C Notes. Such a defeasance would be treated as a taxable exchange for Federal income tax purposes, as a result of which a holder could recognize gain or loss, and which could change the amounts, timing and character of any income, gain or loss recognized on the Series C Notes following defeasance.

S-13





Table of Contents

Global Securities

When the Series C Notes are initially issued, one or more global securities (the Global Securities) will represent the Series C Notes. These Global Securities will have an aggregate principal amount equal to that of the Series C Notes they represent. Each Global Security will be deposited with, or on behalf of, The Depository Trust Company, as depositary (DTC), and registered in the name of Cede & Co., a nominee of DTC.

The Global Securities will bear legends stating the restrictions on exchanges and registration of transfer referred to below and any other matters provided for by the Senior Note Indenture. Please refer to ‘‘Book-Entry System’’ in the accompanying prospectus.

The Global Securities may not be transferred except as a whole (1) by DTC to a nominee of DTC or (2) by a nominee of DTC to DTC or another nominee of DTC or (3) by DTC or any such nominee to a successor of DTC or a nominee of such successor. If (1) DTC is at any time unwilling or unable to continue as depositary or at any time ceases to be a clearing agency registered as such under the Exchange Act and a successor depositary is not appointed by us within ninety days or (2) there shall have occurred and be continuing after any applicable grace periods an Event of Default under the Senior Note Indenture with respect to the Series C Notes represented by such Global Security, we will issue certificated notes in definitive registered form in exchange for the Global Securities representing the Series C Notes. In addition, we may at any time and in our sole discretion determine not to have any Series C Notes in registered form represented by one or more Global Securities and, in such event, will issue certificated notes in definitive form in exchange for the Global Securities representing the Series C Notes. In any such instance, an owner of a beneficial interest in the Global Securities will be entitled to physical delivery in definitive form of certificated notes represented by the Global Securities equal in principal amount to such beneficial interest and to have such certificated notes registered in its name.

Certain Notices

With respect to any Series C Notes represented by a Global Security, notices to be given to the holders of the Series C Notes will be deemed to have been duly given to the holders when given to DTC, or its nominee, in accordance with DTC’s policies and procedures. We believe that DTC’s practice is to inform its participants of any such notice it receives in accordance with its policies and procedures. Persons who hold beneficial interests in the Series C Notes through DTC or its direct or indirect participants may wish to consult with them about how notices and other communications relating to the Series C Notes may be given and received through the facilities of DTC. Neither we nor the Trustee will have any responsibility with respect to those policies and procedures or for any notices or other communications among DTC, its direct and indirect participants and the beneficial owners of the Series C Notes in global form.

With respect to Series C Notes not represented by a Global Security, other notices to be given to the holders of the Series C Notes will be deemed to have been duly given to the holders upon the mailing of such notices to the holders at their respective addresses as they appear on the security register maintained by us or our agent as of the close of business the day before notice is given. Neither the failure to give any notice nor any defect in any notice given to a particular holder will affect the sufficiency of any notice given to another holder.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

The following is a summary of certain anticipated United States federal income tax consequences of the purchase, ownership and disposition of Series C Notes by Non-U.S. Holders (as defined below). Except where noted, this summary deals only with Series C Notes held as capital assets by beneficial owners of the Series C Notes who purchase Series C Notes in this offering at the issue price. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended (Code), regulations promulgated thereunder, and judicial and administrative rulings and decisions now in effect, all of which are subject to change or differing interpretations, possibly with retroactive effect. This summary does not purport to address all aspects of United States federal income taxation that may affect particular investors

S-14





Table of Contents

in light of their individual circumstances, or certain types of investors subject to special treatment under the United States federal income tax laws, such as persons that mark to market their securities, financial institutions, individual retirement and other tax-deferred accounts, tax-exempt organizations, broker-dealers, former U.S. citizens or long-term residents, life insurance companies, persons that hold Series C Notes as part of a hedge against currency or interest rate risks or that hold Series C Notes as part of a straddle, conversion transaction or other integrated investment. This summary does not address the United States federal income tax consequences of the purchase, ownership and disposition of Series C Notes by U.S. Holders (as defined below). In addition, this summary does not address any aspect of state, local or foreign taxation.

For purposes of this summary, a ‘‘U.S. Holder’’ is a beneficial owner of a Series C Note that is, for United States federal income tax purposes:

  an individual citizen or resident of the United States,   a corporation, or other entity treated as a corporation for United States federal income tax purposes, created or organized in or under the laws of the United States, any state or the District of Columbia,   an estate, the income of which is subject to United States federal income taxation regardless of its source, or   a trust, if (1) a court within the United States is able to exercise primary jurisdiction over administration of the trust and one or more U.S. persons have authority to control all substantial decisions of the trust or (2) it has a valid election in effect to be treated as a U.S. person.

For purposes of this summary, a ‘‘Non-U.S. Holder’’ is a beneficial owner of a Series C Note that is not a U.S. Holder or a partnership (including an entity or arrangement treated as a partnership for United States federal income tax purposes).

If a partnership (including an entity or arrangement treated as a partnership for United States federal income tax purposes) is a beneficial owner of Series C Notes, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. Partners of partnerships that are beneficial owners of Series C Notes should consult their tax advisors.

Payments of Interest.    Payments of interest (including OID) on a Series C Note received or accrued by a Non-U.S. Holder generally will qualify for the ‘‘portfolio interest’’ exemption and generally will not be subject to United States federal income tax or withholding tax, as long as the Non-U.S. Holder:

  does not conduct a trade or business in the United States with respect to which the interest is effectively connected,   does not actually, indirectly or constructively own a 10 percent or greater interest in the capital or profits of the Issuer,   is not a ‘‘controlled foreign corporation’’ with respect to which the Issuer is a ‘‘related person’’ within the meaning of Section 881(c)(3)(C) of the Code,   is not a bank whose receipt of the interest is described in Section 881(c)(3)(A) of the Code, and   satisfies the certification requirements described below.

The certification requirements will be satisfied if either (1) the beneficial owner of the Series C Note timely certifies, under penalties of perjury, to the Issuer or to the person who otherwise would be required to withhold U.S. tax that such owner is a Non-U.S. Holder and provides its name and address or (2) a custodian, broker, nominee or other intermediary acting as an agent for the beneficial owner (such as a securities clearing organization, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business) that holds the Series C Note in such capacity timely certifies, under penalties of perjury, to the Issuer or to the person who otherwise would be required to withhold U.S. tax that such statement has been received from the beneficial owner of the Series C Note by such intermediary, or by any other financial institution between such intermediary and the beneficial owner, and furnishes to the Issuer or to the person who otherwise would be required to withhold U.S. tax a copy thereof. The foregoing certification may be provided on a properly completed IRS Form W-8BEN or W-8IMY, as applicable.

S-15





Table of Contents

A Non-U.S. Holder that is not exempt from United States federal income tax or withholding tax under these rules generally will be subject to United States federal withholding at a tax rate of 30 percent unless:

  the income is effectively connected with the conduct of a United States trade or business, (and, if applicable income tax treaty so provides, is attributable to a permanent establishment maintained in the United States by the Non-U.S. Holder) in which case the interest will be subject to United States federal income tax on a net income basis as applicable to U.S. Holders generally (unless an applicable income tax treaty provides otherwise), or   an applicable income tax treaty provides for a lower rate of, or exemption from, withholding tax.

A Non-U.S. Holder that is treated as a corporation for United States federal income tax purposes may also, under certain circumstances, be subject to an additional branch profits tax at a rate of 30 percent (or such lower rate as may be specified by an applicable income tax treaty) on any ‘‘effectively connected’’ interest on the Series C Notes.

To claim the benefit of an income tax treaty or to claim exemption from withholding because income is effectively connected with a United States trade or business, the Non-U.S. Holder must provide the appropriate, properly executed IRS forms in a timely manner. These forms may be required to be periodically updated.

Sale, Exchange or Other Taxable Disposition of a Series C Note.    A Non-U.S. Holder generally will not be subject to United States federal income tax on any gain realized on the sale, exchange, retirement or other disposition of a Series C Note unless (1) such gain is effectively connected with the conduct by the Non-U.S. Holder of a United States trade or business (and, if an applicable income tax treaty so provides, is attributable to a permanent establishment maintained in the United States by the Non-U.S. Holder) or (2) in the case of an Non-U.S. Holder who is an individual, the holder is present in the United States for 183 days or more during the taxable year in which such gain is realized and certain other conditions exist.

Except to the extent that an applicable income tax treaty otherwise provides, generally a Non-U.S. Holder will be taxed in the same manner as a U.S. Holder with respect to gain that is effectively connected with the Non-U.S. Holder’s conduct of a United States trade or business. A Non-U.S. Holder that is treated as a corporation for United States federal income tax purposes may also, under certain circumstances, be subject to an additional ‘‘branch profits tax’’ at a rate of 30 percent (or such lower rate as may be specified by an applicable income tax treaty) on any ‘‘effectively connected’’ gain on the Series C Notes.

Information Reporting and Backup Withholding.    Payments of interest to a Non-U.S. Holder generally will be reported to the IRS and to the Non-U.S. Holder. Copies of applicable IRS information returns may be made available under the provisions of a specific tax treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides. Non-U.S. Holders are generally exempt from backup withholding and additional information reporting on payments of principal, premium (if any), or interest (including OID), provided that the Non-U.S. Holder (1) certifies its nonresident status on the appropriate IRS Form (or a suitable substitute form) and certain other conditions are met or (2) otherwise establishes an exemption. Any backup withholding tax generally will be allowed as a credit or refund against the Non-U.S. Holder’s United States federal income tax liability, if the required information is furnished to the IRS in a timely manner.

UNDERWRITING

J.P. Morgan Securities Inc. and Lehman Brothers Inc. are acting as joint book-running managers and as the representatives of the underwriters named below. Subject to the terms and conditions set forth in the underwriting agreement between us and each of the underwriters named below, dated the date of this prospectus supplement, we have agreed to sell to each of the underwriters, and each of the underwriters have severally, but not jointly, agreed to purchase the principal amount of Series C Notes set forth opposite its name below:


Underwriters Principal Amount
of Series C
Notes
J.P. Morgan Securities Inc. $                  Lehman Brothers Inc.   Banc of America Securities LLC   BNY Mellon Capital Markets, LLC   Wells Fargo Securities, LLC   Total $

In the underwriting agreement, the underwriters have agreed, subject to the terms and conditions set forth therein, to purchase all of the Series C Notes offered hereby if any of the Series C Notes are purchased. The obligations of the underwriters, including their agreement to purchase the Series C Notes from us, are several and not joint. The underwriting agreement provides that the obligations of the underwriters pursuant thereto are subject to certain conditions and to approval of legal matters by counsel.

The underwriters have advised us that they initially propose to offer part of the Series C Notes directly to the public at the public offering price set forth on the cover page hereof and part to certain dealers at a price that represents a concession not in excess of         % of the principal amount of the Series C Notes. The underwriters may allow, and any such dealers may reallow, a concession to certain other dealers not to exceed        % of the principal amount of the Series C Notes. After the initial offering of the Series C Notes, the offering price and other selling terms may from time to time be varied by the underwriters.

The Series C Notes are a new issue of securities with no established trading market. The Series C Notes will not be listed on any securities exchange or on any automated dealer quotation system. The underwriters may make a market in the Series C Notes after completion of the offering, but will not be obligated to do so and may discontinue any market-making activities at any time without notice. No assurance can be given as to the liquidity of the trading market for the Series C Notes or that an active public market for the Series C Notes will develop. If an active public trading market for the Series C Notes does not develop, the market prices and liquidity of the Series C Notes may be adversely affected.

In order to facilitate the offering of the Series C Notes, the representatives may engage in transactions that stabilize, maintain or otherwise affect the price of the Series C Notes. Specifically, the representatives may overallot in connection with the offering of the Series C Notes, creating a short position for its own account. In addition, to cover overallotments or to stabilize the price of the Series C Notes, the representatives may bid for, and purchase, Series C Notes in the open market. Finally, the representatives may reclaim selling concessions allowed to an underwriter or a dealer for distributing the Series C Notes in the offering, if they repurchase previously distributed Series C Notes in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price for the Series C Notes above independent market levels. The representatives are not required to engage in these activities and may end any of these activities at any time without notice.

We estimate that our expenses in connection with the offer and sale of the Series C Notes will be approximately $366,800.

BNY Mellon Capital Markets, LLC is an affiliate of the trustee under the Senior Note Indenture.

EXPERTS

The consolidated financial statements as of December 31, 2007 and 2006, and for each of the three years in the period ended December 31, 2007, and the related consolidated financial statement schedules incorporated in this prospectus supplement and the effectiveness of Northeast Utilities’ internal control over financial reporting have been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their reports (which reports (1) express an unqualified opinion on the consolidated financial statements and consolidated financial statement schedules and include an explanatory paragraph relating to the adoption of Financial Accounting Standards Board Interpretation No. 48, Accounting for Uncertainty in Income Taxes – an Interpretation of FASB Statement No. 109, as of January 1, 2007 and (2) express an unqualified opinion on the effectiveness of internal control over financial reporting). Such consolidated financial statements and consolidated financial statement schedules have been so incorporated in reliance upon the reports of such firm given upon their authority as experts in accounting and auditing.

With respect to the unaudited interim financial information for the periods ended March 31, 2008 and 2007, which is incorporated herein by reference, Deloitte & Touche LLP, an independent registered public accounting firm, have applied limited procedures in accordance with the standards of the Public Company Accounting Oversight Board (United States) for a review of such information. However, as stated in their report included in the Company’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2008 and incorporated by reference herein, they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their reports on such information should be restricted in light of the limited nature of the review procedures applied. Deloitte & Touche LLP are not subject to the liability provisions of Section 11 of the Securities Act of 1933 for their reports on the unaudited interim financial information because those reports are not ‘‘reports’’ or a ‘‘part’’ of the registration statement prepared or certified by an accountant within the meaning of Sections 7 and 11 of the Securities Act of 1933.

SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES
LITIGATION REFORM ACT OF 1995

We make statements in this prospectus and in the documents we incorporate by reference that are statements concerning our expectations, plans, objectives, future financial performance and other statements that are not historical facts. These statements are ‘‘forward looking statements’’ within the meaning of the Private Securities Litigation Reform Act of 1995 (Reform Act). Forward looking statements involve risks and uncertainties that may cause actual results or outcomes to differ materially from those included in the forward looking statements. In connection with the safe harbor provisions of the Reform Act, the Registrants are herein filing cautionary statements identifying important factors that could cause their respective actual results to differ materially from those projected in forward looking statements (as such term is defined in the Reform Act) made by or on behalf of the Registrants. Any statements that express or involve discussions as to expectations, beliefs, plans, objectives, assumptions or future events, performance or growth (often, but not always, through the use of words or phrases such as estimate, expect, anticipate, intend, plan, believe, forecast, should, could and similar expressions) are not statements of historical facts and may be forward looking. Forward looking statements involve estimates, assumptions and uncertainties that could cause actual results to differ materially from those expressed in the forward looking statements. Accordingly, any such statements are qualified in their entirety by reference to, and are accompanied by, the following important factors that could cause a Registrant’s actual results to differ materially from those contained in forward looking statements of such Registrant made by or on behalf of such Registrant.

Some important factors that could cause actual results or outcomes to differ materially from those discussed in the forward looking statements include, but are not limited to, actions by state and federal regulatory bodies, competition and industry restructuring, changes in economic conditions, changes in weather patterns, changes in laws, regulations or regulatory policy, changes in levels and timing of capital expenditures, developments in legal or public policy doctrines, technological developments, changes in accounting standards and financial reporting regulations, fluctuations in the value of our remaining electricity positions, actions of rating agencies, and other presently unknown or unforeseen factors. Other risk factors are detailed from time to time in the Registrants’ reports to the Commission.

All such factors are difficult to predict, contain uncertainties which may materially affect actual results and are beyond the control of the Registrants. Any forward looking statement speaks only as of the date on which such statement is made, and the Registrants undertake no obligation to update any forward looking statement or statements to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events. New factors emerge from time to time and it is not possible for each Registrant’s management to predict all of such factors, nor can such management assess the impact of each such factor on the business of such Registrant or the extent to which any factor, or combination of factors, may cause actual results of such Registrant to differ materially from those contained in any forward looking statements.

DESCRIPTION OF SECURITIES REGISTERED

NORTHEAST UTILITIES

General.    The following description sets forth certain general terms and provisions of the securities being registered by NU to which any prospectus supplement may relate. The description does not purport to be complete. The particular terms of the securities offered by any prospectus supplement and the extent, if any, to which such general provisions may apply to the securities so offered, will be described therein. If there is any inconsistency between the information in this prospectus and the prospectus supplement, you should rely on the information in the prospectus supplement.

Common Shares and Preferred Shares

Common Shares.    Our outstanding common shares are listed on the New York Stock Exchange (NYSE) under the symbol ‘‘NU’’. Any additional common shares we issue will also be listed on the NYSE. Common shareholders may receive dividends if and when declared by our Board of Trustees. Dividends may be paid in cash, shares or other form. All outstanding common shares are fully paid and non-assessable. Any additional common shares we issue will also be fully paid and non-assessable.

Each common share is entitled to one vote in the election of Trustees and other matters. Common shareholders are not entitled to cumulative voting rights. Each common shareholder received one common share purchase right per common share owned under our Shareholder Rights Plan. This plan was adopted in 1999 and will terminate in 2009, unless earlier terminated or extended. This right permits a common shareholder to acquire additional common shares under certain circumstances.

We will notify common shareholders of any shareholders’ meetings according to applicable law. If we liquidate, dissolve or wind up our business, either voluntarily or not, common shareholders will share equally in the assets remaining after we pay our creditors and preferred shareholders, if any.

The Bank of New York is our transfer agent and registrar. You may contact them at their Investor Relations Department, P.O. Box 11258. Church Street Station, New York, NY 10286-1258. Tel.: 1-800-999-7269.

Preferred Shares.    We do not currently have preferred shares authorized, although our Declaration of Trust allows for the issuance of preferred shares subject to common shareholder approval. Before we can issue preferred shares we will need to obtain the authorization of our Board of Trustees and of our common shareholders. If we issue preferred shares, the specific designations and rights will be described in the prospectus supplement and a description will be filed with the Commission. The following description of the terms of the preferred shares sets forth certain general terms and provisions.

Preferred shares will have such par value, if any, such priority in liquidation, such voting rights and such other rights, privileges, preferences, restrictions and limitations as may be established by our Board of Trustees and approved by our common shareholders. In some cases, the issuance of preferred shares could delay a change in control of the Company and make it harder to remove present management. Under certain circumstances, preferred shares could also restrict dividend payments to holders of our common shares.

The preferred shares will, when authorized and issued, be fully paid and non-assessable. Unless otherwise specified in the applicable prospectus supplement, the preferred shares will rank on parity in all respects with any outstanding preferred shares we may have at that time and will have priority over our common shares as to dividends and distributions of assets. Therefore, the rights of any preferred share may limit the rights of the holders of our common shares.

The transfer agent, registrar, and dividend disbursement agent for a series of preferred shares will be named in a prospectus supplement. The registrar for preferred shares will send notices to shareholders of any meetings at which holders of the preferred shares have the right to elect Trustees or to vote on any other matter.

Table of Contents

Warrants

We may issue warrants for the purchase of preferred shares, common shares, or any combination thereof. Warrants may be issued independently or together with other securities and may be attached to or separate from any offered securities. Each series of warrants will be issued under a separate warrant agreement to be entered into between us and a bank or trust company, as warrant agent. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for us with any holders or beneficial owners of warrants.

This summary of certain provisions of the warrants is not complete. For the complete terms of the warrants and the warrant agreement, you should refer to the provisions of the warrant agreement that we will file with the Commission in connection with the offering of such warrants.

The applicable prospectus supplement will describe the following terms of any warrants in respect of which this prospectus is being delivered:

  the title of such warrants;   the aggregate number of such warrants;   the price or prices at which such warrants will be issued;   the currency or currencies, in which the price of such warrants will be payable;   the securities purchasable upon exercise of such warrants and the price at which the securities may be purchased;   the date on which the right to exercise such warrants shall commence and the date on which such right shall expire;   if applicable, the minimum or maximum amount of such warrants which may be exercised at any one time;   if applicable, the designation and terms of the securities with which such warrants are issued and the number of such warrants issued with each such security;   if applicable, the date on and after which such warrants and the related securities will be separately transferable;   information with respect to book-entry procedures, if any;   if applicable, a discussion of any material United States Federal income tax considerations; and   any other terms of such warrants, including terms, procedures and limitations relating to the exchange and exercise of such warrants.

We and the warrant agent may amend or supplement the warrant agreement for a series of warrants without the consent of the holders issued thereunder to effect changes that are not inconsistent with the provisions of the warrants and that do not materially and adversely affect the interests of the holders of the warrants.

Share Purchase Contracts and Share Purchase Units

We may issue share purchase contracts, including contracts obligating holders to purchase from us, and us to sell to the holders, a specified number of common shares at a future date or dates. The price per common share and the number of common shares may be fixed at the time the share purchase contracts are issued or may be determined by reference to a specific formula set forth in the share purchase contracts. The share purchase contracts may be issued separately or as part of units consisting of a share purchase contract and beneficial interests in debt securities, preferred shares or debt obligations of third parties, including U.S. treasury securities or obligations of our subsidiaries, securing the holders’ obligations to purchase the common shares under the share purchase contracts, which we refer to in this prospectus as share purchase units. The share purchase contracts may require

7





Table of Contents

us to make periodic payments to the holders of the share purchase units or vice versa, and these payments may be unsecured or refunded on some basis. The share purchase contracts may require holders to secure their obligations under those contracts in a specified manner.

The applicable prospectus supplement will describe the terms of the share purchase contracts or share purchase units, including, if applicable, collateral or depositary arrangements, relating to the share purchase contracts or share purchase units.

Massachusetts Law and Our Declaration of Trust

General.    We are an unincorporated ‘‘voluntary association’’ formed under Massachusetts law, a type of entity commonly referred to as a Massachusetts business trust. For most purposes, except those explicitly set forth below, a Massachusetts business trust is a common law entity governed solely by our Declaration of Trust, which constitutes a contract among the Trustees and shareholders or beneficiaries of the trust and is comparable to a certificate of incorporation and bylaws of a corporation.

Corporate Governance.    The rights of our shareholders are currently governed by Massachusetts law and our Declaration of Trust. Our Declaration of Trust provides that all matters properly brought before a shareholder meeting at which a quorum is present will be decided by the majority vote of the shares present or represented by proxy at the meeting, except as otherwise set forth in the Declaration of Trust and the provisions of any class or classes of preferred shares that may be authorized. The Declaration of Trust also provides that the Trustees may only be elected with the affirmative vote of the holders of a majority of the outstanding shares with general voting power. A vote of two-thirds of all shares outstanding and having voting power may be required to take certain actions.

Amendments to Governing Documents.    Our Declaration of Trust provides that the trust may be altered, amended, added to or rescinded by the affirmative vote of at least two-thirds of the member of our board of Trustees, provided that any such alteration, amendment, addition or rescission must also be approved by the affirmative vote or the written consent of the holders of at least two-thirds of all shares issued and outstanding and having general voting power. However, no alteration, amendment, addition or rescission adversely affecting the preferences or priorities of any preferred shares will be effective without the affirmative vote or written consent of the holders of at least two-thirds of the affected preferred shares.

Preemptive Rights.    Our Declaration of Trust provides that the holders of common shares and convertible securities will have preemptive rights with respect to offerings for cash of common shares or securities convertible into common shares, except with respect to:

  common shares, or the grant of rights or options on such shares, to our Trustees, directors, officers, or employees or those of a subsidiary of ours, if the issue or grant is approved by the holders of common shares at a meeting duly held for such purpose or is authorized by and consistent with a plan previously so approved by the holders of common shares;   common shares issued on the conversion of convertible securities, if the convertible securities were offered or issued to holders of common shares in satisfaction of their preemptive rights or were not subject to preemptive rights;   common shares and convertible securities offered to shareholders in satisfaction of their preemptive rights and not purchased by those shareholders;   common shares or convertible securities issued pursuant to a plan adjusting any rights to fractional shares or fractional interests in order to prevent the issue of fractional shares or fractional interests in these shares;   common shares or convertible securities issued in connection with a merger or consolidation or pursuant to an order of a court, unless such order provides otherwise;   common shares or convertible securities issued in a public offering or through an underwriting;

8





Table of Contents   common shares or convertible securities released from preemptive rights through the affirmative vote or written consent of the holders of at least two-thirds of the common shares then outstanding; or   common shares or convertible securities held in our treasury.

Board of Trustees.    Members of our Board of Trustees serve one-year terms and are elected annually.

Shareholder Proposals and Trustee Nominations.    Our shareholders may submit shareholder proposals and nominate candidates for the Board of Trustees if the shareholders follow advance notice procedures described in our annual proxy statement.

Meetings of Shareholders.    Under our Declaration of Trust, meetings of the shareholders may be called only by the chairman of the board, the president, or a majority of the Board of Trustees or may be requested by the holders of one-tenth (1/10) in interest of all shares outstanding having a right to vote.

Indemnification Of Trustees And Officers.    Our Declaration of Trust provides that we will indemnify each of its present and former Trustees and officers against any loss, liability or expense incurred in proceedings in which such person may be involved by reason of being or having been an officer or Trustee, except with respect to any matter as to which such person shall have been finally adjudicated in such proceeding not to have acted in good faith in the reasonable belief that such person’s action was in our best interests. If any such proceeding is disposed of by a compromise payment by any such Trustee or officer, no indemnification payment will be provided unless a determination is made that such officer or Trustee acted in good faith in the reasonable belief that such person’s action was in our best interests. Such determination must be made by either the Board of Trustees by majority vote of the quorum consisting of Trustees who were not parties to such proceeding, by our independent legal counsel in a written opinion, or by the shareholders.

Limitation On Trustee Liability.    The Declaration of Trust provides that no member of the Board of Trustees will be liable to us or our shareholders for monetary damages due to any breach of fiduciary duty, except for:

  breaches of such person’s duty of loyalty to us or our shareholders;   acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; or   any transaction from which such person derived an improper personal benefit.

Anti-takeover Statutes.    A Massachusetts anti-takeover statute, Chapter 110F of the Massachusetts General Laws, prohibits any business combination with an interested shareholder, generally a person who owns or has recently owned at least 5% of the company’s outstanding voting shares, for three years after the person becomes an interested shareholder unless:

  prior to the 5% purchase, the Board of Trustees approves either the 5% purchase or the proposed business combination;   the interested shareholder owned approximately 90% of the company’s voting shares after making the 5% purchase which rendered him or her an interested shareholder; or   the Board of Trustees and holders of two-thirds of the non-interested shares approve the business combination after the acquiror has become an interested shareholder.

Another Massachusetts anti-takeover statute, Chapter 110D of the Massachusetts General Laws, regulates the acquisition of control shares. A control share acquisition occurs when an individual aggregates a number of shares which, when added to shares already owned, would allow the acquiring person to vote at least 20% of the company’s shares. Under Chapter 110D, shares acquired in this type of a transaction would have no voting rights unless a majority of non-interested shareholders specifically voted to grant the acquiring person voting rights for these shares. In general, the acquiring person as well as our officers and employee-Trustees are not permitted to vote on whether these voting rights should be granted.

Table of Contents

Our Declaration of Trust does not address anti-takeover regulations or protections, though as noted above, we adopted a Shareholder Rights Plan in 1999 which permits a common shareholder to acquire additional common shares under certain circumstances.

Senior Notes

General.    The following description sets forth certain general terms and provisions of the senior unsecured notes being registered by NU (Senior Notes). The description does not purport to be complete and is subject to, and qualified in its entirety by, all of the provisions of the Senior Note Indenture (as defined below), which is incorporated herein by reference and is an exhibit to the Registration Statement of which this prospectus is a part. The particular terms of the Senior Notes offered by any prospectus supplement and the extent, if any, to which such general provisions may apply to the Senior Notes so offered will be described therein. References to section numbers under this caption are references to the section numbers of the Senior Note Indenture. Capitalized terms not defined herein have the meanings given to them in the Senior Note Indenture.

Senior Notes will be issued under a supplemental indenture or indentures to our indenture (the Senior Note Indenture), between us and The Bank of New York Trust Company, N.A., as successor trustee (the Senior Note Trustee) dated as of April 1, 2002, as amended and supplemented. You may contact them at their Corporate Trust Administration Office at 222 Berkley Street, 2nd Floor, Boston, MA 02216, Tel. (617) 273-8368.

The Senior Notes will be our senior unsecured debt securities and will rate equally with all of our other unsecured and unsubordinated debt. There is no requirement under the Senior Note Indenture that future issues of our debt securities be issued under the Senior Note Indenture, and we will be free to use other indentures or documentation, containing provisions different from those included in the Senior Note Indenture or applicable to one or more issues of Senior Notes, in connection with future issues of such other debt securities.

The Senior Note Indenture does not limit the aggregate principal amount of the Senior Notes that may be issued thereunder. The Senior Note Indenture provides that the Senior Notes will be issued in one or more series as notes or debentures. The Senior Notes may be issued at various times and may have differing maturity dates and may bear interest at differing rates. The prospectus supplement applicable to each issue of Senior Notes will specify:

  the designation and aggregate principal amount of such Senior Notes;   the date or dates on which such Senior Notes will mature;   the interest rate or rates, or method of calculation of such rate or rates, on such Senior Notes, and the date from which such interest shall accrue;   the dates on which such interest will be payable or method by which such dates are to be determined;   the record dates for payments of interest;   any redemption terms;   the period or periods within which, the price or prices at which, and the terms and conditions upon which, such Senior Notes may be repaid, in whole or in part, at our option;   the place or places, if any, in addition to or in the place of our office or the office of the Senior Note Trustee, where the principal of (and premium, if any) and interest, if any, on such Senior Notes shall be payable and where notices to us shall be sent; and   other specific terms applicable to such Senior Notes. (Section 301)

Unless otherwise indicated in the applicable prospectus supplement, the Senior Notes will be denominated in United States currency in minimum denominations of $1,000 and integral multiples thereof. (Section 301)

Unless otherwise indicated in the applicable prospectus supplement or as below described under Limitation on Liens and ‘‘Sale and Leaseback Transactions’’, there are no provisions in the Senior

10





Table of Contents

Note Indenture or the Senior Notes that require us to redeem, or permit the holders of the Senior Notes to cause a redemption of, the Senior Notes or that otherwise protect the holders of the Senior Notes in the event that we incur substantial additional indebtedness, whether or not in connection with a change in control of us.

Because we are a holding company that conducts all of our operations through our subsidiaries, our ability to meet our obligations under the Senior Notes is dependent on the earnings and cash flows of those subsidiaries and the ability of those subsidiaries to pay dividends to us, repurchase shares of their common stock from us or repay loans or advances made by us to them. Holders of the Senior Notes will generally have a junior position to claims of any holders of preferred stock and creditors of our subsidiaries, including trade creditors, debtholders, secured creditors, taxing authorities and guarantee holders. In addition to trade debt, our subsidiaries have ongoing corporate debt programs used to finance their business activities. Unless otherwise specified in a prospectus supplement, the Supplemental Indentures will not limit the amount of indebtedness or preferred stock issuable by our subsidiaries.

Registration, Transfer, Exchange and Form.    Senior Notes of any series may be exchanged for other Senior Notes of the same series of any authorized denominations and of a like aggregate principal amount and tenor. (Section 305)

Unless otherwise indicated in the applicable prospectus supplement, Senior Notes may be presented for registration of transfer (duly endorsed or accompanied by a duly executed written instrument of transfer) at the office or agency maintained for such purpose with respect to any series of Senior Notes and referred to in the applicable prospectus supplement, without service charge and upon payment of any taxes and other governmental charges as described in the Senior Note Indenture. (Section 305)

In the event of any redemption of Senior Notes of any series, we will not be required to exchange, or register the transfer of, any Senior Notes of such series selected, called or being called for redemption except, in the case of any Senior Note to be redeemed in part, the portion thereof not to be so redeemed. (Section 305)

Paying Agents.    We will maintain an office or agency where Senior Notes may be presented or surrendered for payment. We will give prompt written notice to the Senior Note Trustee of the location, and any change in the location, of such office or agency. If at any time we shall fail to maintain any such required office or agency or shall fail to furnish the Senior Note Trustee with the address thereof, such presentations and surrenders may be made or served at the corporate trust office of the Senior Note Trustee, and, in such event, the Senior Note Trustee shall act as our agent to receive all such presentations and surrenders. (Section 1002)

All monies paid by us to a paying agent for the payment of principal of, interest or premium, if any, on any Senior Note which remains unclaimed at the end of two years after any such principal, interest or premium shall have become due and payable will be repaid to us at our request and the Holder of such Senior Note will thereafter look only to us for payment thereof as an unsecured general creditor. (Section 1003)

Consolidation, Merger, Conveyance, Sale or Transfer.    Nothing contained in the Senior Note Indenture prevents us from consolidating with or merging into another corporation or conveying, selling or otherwise transferring our properties and assets substantially as an entirety to any Person, provided that:

  the corporation formed by such consolidation or into which we are merged or the Person which acquires by conveyance, sale or transfer our properties and assets substantially as an entirety is a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and expressly assumes by an indenture supplemental thereto, executed and delivered to the Senior Note Trustee, in form satisfactory to the Senior Note Trustee, the due and punctual payment of the principal of (and premium, if any) and interest, if any, on all the Senior Notes and the performance of every covenant of the Senior Note Indenture on our part to be performed or observed; and

11





Table of Contents   immediately after giving effect to the transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have occurred and be continuing.

We shall also be required to deliver to the Senior Note Trustee certificates and opinions stating that such consolidation, merger, conveyance, sale or transfer comply with the Senior Note Indenture and all relevant conditions precedent have been satisfied. (Section 801)

Limitation on Liens.    Nothing contained in the Senior Note Indenture or in the Senior Notes in any way restricts or prevents us or any of our subsidiaries from incurring any indebtedness; provided that if this covenant is made applicable to the Senior Notes of any particular series, we will not issue, assume or guarantee (including any contingent obligation to purchase) or permit to exist any notes, bonds, debentures or other evidences of indebtedness for money borrowed (Debt) secured by a mortgage, lien, pledge, security interest or other encumbrance (Lien) upon any of our property, including the capital stock of any of our subsidiaries, without effectively providing that the outstanding Senior Notes (together with, if we so determine, any other indebtedness or obligation then existing or thereafter created ranking equally with the Senior Notes) shall be secured equally and ratably with (or prior to) such Debt so long as such Debt shall be so secured (provided that for purposes of providing such equal and ratable security, the principal amount of outstanding Senior Notes of any series will be such portion of the principal amount as may be specified in the terms of such series). This restriction will not, however, apply to

  Liens in existence on the date of the original issue of the Senior Notes to which this restriction is made applicable, including, without limitation, ‘‘stock forward’’ transactions;   Liens created solely for the purpose of securing Debt incurred to finance, refinance or refund the purchase price or cost (including the cost of construction) of property acquired after the date hereof (by purchase, construction or otherwise), or Liens in favor of guarantors of obligations or Debt representing, or incurred to finance, refinance or refund, such purchase price or cost, provided that no such Lien shall extend to or cover any property other than the property so acquired and improvements thereon and provided further that such Liens are created no later than 24 months after the purchase or construction;   Liens on any property or assets acquired from a corporation which is merged with or into us, which Liens are not created as a result of or in connection with or in anticipation of any such merger (unless such Liens were created to secure or provide for the payment of any part of the purchase price of such corporation);   any Lien on any property or assets existing at the time of acquisition thereof and which is not created as a result of or in connection with or in anticipation of such acquisition (unless such Lien was created to secure or provide for the payment of any part of the purchase price of such property or assets); or   any extension, renewal or replacement of any Lien referred to in the foregoing clauses, provided that the principal amount of Debt so secured thereby shall not exceed the principal amount of Debt so secured at the time of such extension, renewal or replacement, and that such extension, renewal or replacement Lien shall be limited to all or part of substantially the same property which secured the Lien extended, renewed or replaced (plus improvements on such property).

Notwithstanding the foregoing, we may issue or assume Debt secured by Liens on our cash which would otherwise be subject to the foregoing restrictions in an aggregate principal amount which does not at the time of issuance or assumption exceed $100 million. The following types of transactions shall not be deemed to create Debt secured by Liens: Liens required by any contract or statute in order to permit us to perform any contract or subcontract made by it with or at the request of a governmental entity or any department, agency or instrumentality thereof, or to secure partial, progress, advance or any other payments to us by such governmental unit pursuant to the provisions of any contract or statute; and share forwards with respect to our common shares accounted for as equity transactions under applicable accounting guidelines wherein the shares collateralize the forward repayment obligation. (Section 1007)

Sale and Leaseback Transactions.    If this covenant is made applicable to the Senior Notes of any series, we will not enter into any Sale and Leaseback Transaction unless either:

  we would be entitled pursuant to the ‘‘Limitation on Liens’’ covenant above to create Debt secured by a Lien on the property to be leased back in an amount equal to the Attributable Value of such Sale and Leaseback Transaction without the Senior Notes being effectively secured equally and ratably with (or prior to) that Debt; or   we, within 270 days after the sale or transfer of the relevant assets shall have been made, apply, in the case of a sale or transfer for cash, an amount equal to the net proceeds from the sale or, in the case of a sale or transfer otherwise than for cash, an amount equal to the fair market value of the property so leased (as determined by any two of our Trustees) to:   the retirement of our long-term indebtedness ranking prior to or on a parity with the Senior Notes or   The investment in any property used in the ordinary course of our business.

‘‘Attributable Value’’ means, as to any particular lease under which we are at any time liable as lessee and at any date as of which the amount thereof is to be determined, the amount equal to the greater of (i) the net proceeds from the sale or transfer of the property leased pursuant to the Sale and Leaseback Transaction or (ii) the net book value of the property, as determined by us in accordance with generally accepted accounting principles at the time of entering into the Sale and Leaseback Transaction, in either case multiplied by a fraction, the numerator of which shall be equal to the number of full years of the term of the lease that is part of the Sale and Leaseback Transaction remaining at the time of determination and the denominator of which shall be equal to the number of full years of the term, without regard, in any case, to any renewal or extension options contained in the lease.

‘‘Sale and Leaseback Transaction’’ means any transaction or series of related transactions relating to property now owned or hereafter acquired by us whereby we transfers the property to a person and we lease it from that person for a period, including renewals, in excess of 36 months. (Section 1012)

Modification of the Senior Note Indenture.    The Senior Note Indenture contains provisions permitting us and the Senior Note Trustee, with the consent of the holders of a majority in principal amount of the outstanding Senior Notes, of all series affected by the modification (voting as one class), to modify the Senior Note Indenture or any supplemental indenture or the rights of the holders of the Senior Notes of such series; provided that no such modification shall without the consent of the holders of each outstanding Senior Note affected thereby:

  Change the date upon which the principal of or the interest on any Senior Note is due and payable;   reduce the principal amount thereof or the rate of interest thereon or any premium payable upon the redemption thereof;   change any place of payment where, or the currency in which, any Senior Note or any premium or the interest thereon is payable;   impair the right to institute suit for the enforcement of any payment on or after the date such payment is due (or, in the case of redemption, on or after the date fixed for such redemption);   reduce the aforesaid percentage of Senior Notes, the consent of the holders of which is required for any modification of the applicable supplemental indenture or for waiver by the holders of certain of their rights; or   Modify certain provisions of the Senior Note Indenture. (Section 902)

The Senior Note Indenture also contains provisions permitting us and the Senior Note Trustee to amend the Senior Note Indenture in certain circumstances without the consent of the holders of any Senior Notes to evidence the succession of another Person to us, the replacement of the Senior Note

Table of Contents

Trustee and for certain other purposes, including to cure any ambiguity or defect, or correct any inconsistency, in the Senior Note Indenture, or to add or change any other provisions with respect to matters or questions arising under the Senior Note Indenture or the Senior Notes, provided such changes or additions shall not adversely affect the interests of the holders of any series of the Senior Notes in any material respect, or involve a change requiring the consent of the holders of the Senior Notes described in the preceding paragraph. (Section 901)

Events of Default.    An Event of Default with respect to the Senior Notes is defined in the Senior Note Indenture as being:

  Failure to pay any interest on the Senior Notes and continuance of such failure for 30 days;   failure to pay the principal (or premium, if any), including the payment of principal (or premium, if any) when due pursuant to any redemption provision of the Senior Notes and continuance of such failure for three days;   failure to pay any sinking fund installment, if any, pursuant to the terms of the Senior Notes, and continuance of such failure for a period of three days;   default in the performance, or breach, of any covenant or warranty of ours in the Senior Note Indenture (other than certain covenants or warranties a default in whose performance or whose breach is specifically dealt with elsewhere in the Senior Note Indenture or which has been expressly included in the Senior Note Indenture solely for the benefit of any series of Senior Notes other than that series) and continuance of such default or breach for a period of 90 days after written notice is given to us by the Senior Note Trustee or to us and the Senior Note Trustee by the holders of 33% or more in aggregate principal amount of the outstanding Senior Notes; and   certain events of bankruptcy, insolvency, reorganization, receivership or liquidation involving us. (Section 501)

We will be required to file with the Senior Note Trustee annually an officers’ certificate as to the existence or absence of default in performance of certain covenants in the Senior Note Indenture. (Section 1008) The Senior Note Indenture provides that the Senior Note Trustee may withhold notice to the holders of the Senior Notes of any default (except in payment of principal of (or premium, if any), or interest, if any, on, the Senior Notes or in the payment of any sinking fund installment with respect to the Senior Notes) if the Senior Note Trustee in good faith determines that it is in the interest of the holders of the Senior Notes to do so. (Section 602) The Senior Note Indenture provides that, if an Event of Default due to the default in payment of principal of (or premium, if any) or interest on the Senior Notes or in the payment of any sinking fund installment with respect to the Senior Notes, or due to the default in the performance or breach of any covenant or warranty in the Senior Note Indenture by us shall have happened and be continuing, either the Senior Note Trustee or the holders of 33% or more in aggregate principal amount of the outstanding Senior Notes may declare the principal amount of all the Senior Notes to be due and payable immediately, but if we shall cure all defaults and certain other conditions are met, such declaration may be annulled and past defaults may be waived by the holders of a majority in aggregate principal amount of the Senior Notes. If an Event of Default due to certain events of bankruptcy, insolvency or reorganization has occurred and is continuing, the principal amount of all the Senior Notes shall be immediately due and payable, without any act of either the Senior Note Trustee or the holders. (Sections 502 and 513)

Subject to the provisions of the Senior Note Indenture relating to the duties of the Senior Note Trustee, the Senior Note Trustee will be under no obligation to exercise any of its rights or powers under the Senior Note Indenture at the request or direction of any of the holders of the Senior Notes, unless such holders shall have offered to the Senior Note Trustee reasonable indemnity. (Section 603)

Subject to such provision for indemnification, the holders of a majority in principal amount of the Senior Notes will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Senior Note Trustee, or exercising any trust or power conferred on the Senior Note Trustee with respect to the Senior Notes, provided, however, that if an Event of

14





Table of Contents

Default shall have occurred and be continuing with respect to less than all of the series of Senior Notes, the holders of a majority in aggregate principal amount of the Senior Notes of all such series, considered as one class, shall have the right to make such direction, and provided that the Senior Note Trustee shall have the right to decline to follow any such direction if the Senior Note Trustee shall determine that the action so directed conflicts with any law or the provisions of the Senior Note Indenture or if the Senior Note Trustee shall determine that such action would subject the Senior Note Trustee to personal liability or expense for which reasonable indemnity has not been provided. (Section 512)

Defeasance.    We, at our option, (a) will be Discharged from any and all obligations in respect of the Senior Notes (except for certain obligations to register the transfer or exchange of Senior Notes, replace destroyed, stolen, lost or mutilated Senior Notes, maintain paying agencies and hold moneys for payment in trust) or (b) need not comply with certain covenants of the Senior Note Indenture described under ‘‘— Consolidation, Merger, Conveyance, Sale or Transfer’’ and ‘‘— Limitation of Liens’’ or to certain covenants relating to corporate existence and maintenance of properties and insurance, in each case, if:

  We irrevocably deposit with the Senior Note Trustee, in trust, (a) money; or (b) in certain cases, U.S. Government Obligations which through the payment of interest and principal in respect thereof in accordance with their terms will provide money; or (c) a combination thereof, in each case sufficient to pay and discharge   the principal of (and premium, if any) and each installment of principal (and premium, if any) and interest, if any, on the outstanding Senior Notes on the dates such payments are due, in accordance with the terms of the Senior Notes, or to and including the redemption date irrevocably designated by us; and   any mandatory sinking fund payments applicable to the Senior Notes on the day on which payments are due and payable in accordance with the terms of the Senior Note Indenture and of the Senior Notes;   no Event of Default or event which with notice or lapse of time would become an Event of Default shall have occurred and be continuing on the date of such deposit;   we deliver to the Senior Note Trustee an opinion of counsel to the effect   that the holders of the Senior Notes will not recognize income, gain, loss or expense for Federal income tax purposes as a result of such deposit and defeasance of certain obligations;   that such provision would not cause any outstanding Senior Notes then listed on any national securities exchange to be delisted as a result thereof; and   that the defeasance trust is not, or is registered as, an investment company under the Investment Company Act of 1940; and   we have delivered to the Senior Note Trustee an officers’ certificate and an opinion of counsel, each stating that all conditions precedent provided for in the Senior Note Indenture relating to the satisfaction and discharge of the Senior Notes have been complied with. (Sections 403 and 1009)

Discharged means, with respect to the Senior Notes of any series, the discharge of the entire indebtedness represented by, and obligations of ours under, the Senior Notes of such series and in the satisfaction of all the obligations of ours under the Senior Note Indenture relating to the Senior Notes of such series, except:

  the rights of holders of the Senior Notes of such series to receive, from the trust fund established pursuant to the Senior Note Indenture, payment of the principal of and interest and premium, if any, on the Senior Notes of such series when such payments are due;

15





Table of Contents   our obligations with respect to the Senior Notes of such series with respect to registration, transfer, exchange and maintenance of a place of payment; and   the rights, powers, trusts, duties, protections and immunities of the Senior Note Trustee under the Senior Note Indenture. (Section 101)

U.S. Government Obligations means direct obligations of the United States for the payment of which its full faith and credit is pledged, or obligations of a person controlled or supervised by and acting as an agency or instrumentality of the United States and the payment of which is unconditionally guaranteed by the United States, and shall also include a depository receipt issued by a bank or trust company as custodian with respect to any such U.S. Government Obligation or a specific payment of interest on or principal of any such U.S. Government Obligation held by such custodian for the account of a holder of a depository receipt; provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depository receipt from any amount received by the custodian in respect of the U.S. Government Obligation or the specific payment of interest on or principal of the U.S. Government Obligation evidenced by such depository receipt. (Section 101)

Resignation or Removal of Senior Note Trustee.    The Senior Note Trustee may resign at any time upon written notice to us, and such resignation will take effect immediately upon the appointment of a successor Senior Note Trustee. (Sections 610 and 611)

The Senior Note Trustee may be removed at any time by an instrument or concurrent instruments in writing delivered to the Senior Note Trustee and us and signed by the holders, or their attorneys-in-fact, of at least a majority in principal amount of the then outstanding Senior Notes. In addition, under certain circumstances, we may remove the Senior Note Trustee upon notice to the Holder of each Senior Note outstanding and the Senior Note Trustee, and appointment of a successor Senior Note Trustee. (Section 610)

No Recourse Against Others.    The Senior Note Indenture provides that no recourse for the payment of the principal of or any premium or interest on any Senior Note, or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of ours, contained in the Senior Note Indenture or in any supplemental indenture, or in any Senior Note, or because of the creation of any indebtedness represented thereby, will be had against any Trustee, incorporator, stockholder, officer or director, as such, past, present or future, of ours or any successor corporation, either directly or through us or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is expressly waived and released as a condition of, and in consideration for, the execution of the Senior Note Indenture and the issuance of the Senior Notes. (Section 114) Such waiver may not be effective to waive liabilities under the Federal securities laws and we understand that it is the view of the Commission that such a waiver is against public policy.

Concerning the Senior Note Trustee.    The Senior Note Trustee under the Senior Note Indenture or affiliates of the Senior Note Trustee, are also trustees under other indentures and trust agreements of affiliates of ours and registrar and transfer agent of our Common Shares. In addition, an affiliate of the Senior Note Trustee is a lending party to two of our system revolving credit facilities with total commitment amounts under each facility of approximately $34.9 million and $67.7 million.

THE CONNECTICUT LIGHT AND POWER COMPANY

The CL&P Bonds

General.    The following description sets forth certain general terms and provisions of the first and refunding mortgage bonds CL&P may issue under the CL&P Indenture (as defined below) (CL&P Bonds) to which any prospectus supplement may relate. The description does not purport to be complete and is subject to, and qualified in its entirety by, all of the provisions of the CL&P Indenture (as defined below), which is incorporated herein by reference and is an exhibit to the Registration Statement of which this prospectus is a part. The particular terms of the CL&P Bonds offered by any prospectus supplement and the extent, if any, to which such general provisions may apply to the CL&P Bonds so offered, will be described therein. If there is any inconsistency between the information in this prospectus and the prospectus supplement, you should rely on the information in the prospectus supplement.

We will issue the CL&P Bonds in one or more series under our Indenture of Mortgage and Deed of Trust, between us and Deutsche Bank Trust Company Americas (formerly known as Bankers Trust Company), as trustee (the CL&P Bond Trustee), dated as of May 1, 1921, as amended and restated and supplemented and as it is to be further supplemented by one or more Supplemental Indentures, each of which would relate to one or more series of the CL&P Bonds. In this prospectus, we will refer to the Indenture of Mortgage and Deed of Trust, as amended and restated and supplemented, as the ‘‘CL&P Indenture’’ and we will refer to any Supplemental Indenture that will supplement the Indenture as a ‘‘Supplemental Indenture.’’

Amendment and Restatement of the CL&P Indenture.    The CL&P Indenture was amended and restated substantially in its entirety on April 7, 2005. Certain provisions of such amendment (the B Provisions), however, require the consent of the holders of 100% in principal amount of all CL&P Bonds outstanding under the CL&P Indenture in order to become effective. The B Provisions will become effective automatically upon receipt of such requisite 100% consent. We have already obtained the required approval for the B Provisions from the Connecticut Department of Public Utility Control (DPUC).

Each holder of CL&P Bonds issued after 2003 (including any CL&P Bonds offered by any prospectus supplement and any CL&P Bonds offered by any future prospectus), solely by virtue of its acquisition of such CL&P Bonds, including as an owner of a book-entry interest therein, will have and be deemed to have consented, without the need for any further action or consent by such holder, to the B Provisions. We presently do not expect to receive the requisite 100% consent for the B Provisions, and therefore do not expect the B Provisions to become effective, until 2031, when the last two series of CL&P Bonds outstanding issued before 2004 mature.

Accordingly, presented below are summary descriptions of the CL&P Bonds and the CL&P Indenture — as now in effect and as they will be in effect following receipt of the requisite bondholder consent, when the B Provisions become effective.

THERE ARE MATERIAL DIFFERENCES BETWEEN THE CL&P INDENTURE AS NOW IN EFFECT AND AS IT WILL BE IN EFFECT WHEN THE B PROVISIONS BECOME EFFECTIVE, AND YOU ARE ADVISED TO CAREFULLY READ THE SUMMARIES BELOW TO UNDERSTAND THE IMPACT OF THE B PROVISIONS. THE SUMMARY DESCRIPTION OF THE PROVISIONS OF THE CL&P INDENTURE AND OF THE B PROVISIONS WHICH FOLLOWS DOES NOT PURPORT TO BE COMPLETE OR TO COVER ALL OF THE PROVISIONS THEREOF. COPIES OF THE CL&P INDENTURE, INCLUDING THE B PROVISIONS, ARE AVAILABLE FROM US AND REFERENCE IS MADE TO THE CL&P INDENTURE, INCLUDING THE B PROVISIONS, FOR A COMPLETE STATEMENT OF THE APPLICABLE PROVISIONS. THE CL&P INDENTURE, INCLUDING THE B PROVISIONS, IS INCLUDED AS AN EXHIBIT TO THE REGISTRATION STATEMENT OF WHICH THIS PROSPECTUS IS A PART.

General Terms of the CL&P Bonds.    The prospectus supplement with respect to each series of CL&P Bonds will set forth the maturity date, interest rate, interest payment dates, record dates and other specific terms and provisions for such series.

17





Table of Contents

The CL&P Bonds are to be issued only in the form of fully registered bonds without coupons in denominations of $1,000 or multiples thereof and may be presented for exchange for a like aggregate principal amount of the same series of CL&P Bonds of other authorized denominations and for transfer at the principal office of the CL&P Bond Trustee in New York City without payment in either case of any charge other than for any tax or other governmental charges required to be paid by us.

Security.    The CL&P Indenture constitutes a first mortgage lien (subject to liens permitted by the CL&P Indenture) on substantially all of our physical property and franchises, including our generating stations, if any are acquired in the future, and our transmission and distribution facilities. We currently do not own any generating stations. Subject to the provisions of the Federal Bankruptcy Code, the CL&P Indenture will also constitute a lien on after-acquired property, although in states other than Connecticut it may be necessary to comply with applicable recording requirements to perfect the lien on after-acquired property. The CL&P Indenture also permits after-acquired property to be subject to liens prior to that of the CL&P Indenture. The security afforded by the CL&P Indenture is for the equal and ratable protection of all our presently outstanding CL&P Bonds and any CL&P Bonds which may hereafter be issued under the CL&P Indenture.

The B Provisions would continue the existing first mortgage lien of the CL&P Indenture, but would expand both the types of property excepted from the lien and the types of permitted liens. We believe that these changes will not have a material effect on the security afforded by the mortgage lien on the property subject thereto. However, the B Provisions also would exclude any generating properties from the lien of the CL&P Indenture. Although this is not significant at present because we own no generating properties, if any such properties are acquired or constructed in the future, after effectiveness of the B Provisions, such properties would not be subject to the lien of the CL&P Indenture unless we chose to take such action.

Unlike the current provisions of the CL&P Indenture, the B Provisions would permit us to issue certain debt other than CL&P Bonds that would be secured by liens on the mortgaged property that are equal with or prior to the lien of the CL&P Indenture. We believe that this change will not have a material effect on the security provided by the CL&P Indenture, because we may only issue such equal or prior secured debt in an aggregate principal amount up to 3% of the sum of (1) the lesser of the depreciated cost or fair market value of our property then subject to the lien of the CL&P Indenture, plus (2) certain cash then on deposit with the CL&P Bond Trustee. This issuance requirement would not apply to our assumption of debt secured by a lien existing (or created concurrently) on property we acquire, and there would be no limit on the amount of equal or prior secured debt that we could so assume. However, the test for the issuance of additional CL&P Bonds, as described below under ‘‘— Issuance Test for New CL&P Bonds,’’ in effect, counts all outstanding equal or prior secured debt against our ability to issue additional CL&P Bonds.

Under certain limited circumstances, the lien of the CL&P Indenture on real property in Connecticut acquired by us after June 3, 1985 could be subordinated to a lien in favor of the State of Connecticut pursuant to a Connecticut law (Connecticut General Statutes Section 22a-452a) providing for such a lien for reimbursement for expenses incurred in containing, removing or mitigating hazardous waste. Although we presently own no property outside of Connecticut, if we acquire such property it is likely that comparable environmental lien subordination statutes would apply to any such property in other states.

Redemption Provisions.    Unless otherwise provided in the Supplemental Indenture under which a series of the CL&P Bonds is issued and the related prospectus supplement, each series of CL&P Bonds will be redeemable at our option as a whole or in part at any time upon at least 30 days’ prior written notice given by mail as provided in the CL&P Indenture at redemption prices (expressed in percentages of principal amount) that will be set forth in the Supplemental Indenture and the prospectus supplement with respect to such series, together in each case with accrued and unpaid interest to the redemption date.

Issuance Test for New CL&P Bonds.    The CL&P Indenture permits issuance of new CL&P Bonds under the CL&P Indenture in an unlimited amount so long as, after giving effect to such issue, the aggregate amount of all outstanding CL&P Bonds and ‘‘secured debt’’ (generally, debt

18





Table of Contents

secured by a lien equal with or prior to the lien of the CL&P Indenture) in each case outstanding on the issuance date, does not exceed 75% of the sum of (1) the lesser of the depreciated cost or fair market value of our property then subject to the lien of the CL&P Indenture and (2) certain cash then on deposit with the CL&P Bond Trustee in each case calculated as of the most recent balance sheet date.

Sinking and Improvement Fund.    The CL&P Indenture does not contain a sinking and improvement fund requirement.

Replacement Fund.    The CL&P Indenture does not contain a replacement fund requirement.

Withdrawal or Application of Cash.    Cash deposited with the CL&P Bond Trustee can be applied or withdrawn by us at any time so long as there is no default under the CL&P Indenture and so long as, after giving effect to such withdrawal, we could then issue at least $1.00 of additional CL&P Bonds under the test for the issuance of additional CL&P Bonds (described above under ‘‘Issuance Test for New CL&P Bonds’’).

Release of Property.    Property may be released upon compliance with the same requirements applicable to the withdrawal of cash deposited with the CL&P Bond Trustee described above under ‘‘Withdrawal or Application of Cash.’’ The CL&P Indenture also permits dispositions of certain obsolete property and grants or surrender of certain rights without any release or consent by the CL&P Bond Trustee. If we retain any interest in any property released from the lien of the CL&P Indenture, the CL&P Indenture will not constitute a lien on such property or such interest therein or any improvements, extensions or additions to such property or renewals, replacements or substitutions of or for such property or any part or parts thereof.

The B Provisions would provide simplified procedures for the release of minor properties.

Dividend Restrictions.    The CL&P Indenture does not contain a dividend restriction.

Default.    The CL&P Indenture provides that the following events will constitute ‘‘events of default’’ thereunder: (i) failure to pay principal; (ii) failure for 90 days to pay interest; (iii) failure to perform any of the other CL&P Indenture covenants for 90 days after notice to us; (iv) certain events of bankruptcy, insolvency or receivership, and (v) any other event or occurrence specified as an ‘‘event of default’’ in the terms of a particular series of CL&P Bonds. The CL&P Indenture requires us to deliver to the CL&P Bond Trustee an annual officer’s certificate as to compliance with certain provisions of the CL&P Indenture.

The CL&P Indenture provides that, if any event of default exists, the holders of a majority in principal amount of the CL&P Bonds outstanding may, after tender to the CL&P Bond Trustee of indemnity satisfactory to it, direct the sale of the mortgaged property.

Modification of the CL&P Indenture.    The CL&P Indenture may be supplemented or amended to convey additional property, to state indebtedness of companies merged, to add further limitations to the CL&P Indenture, to evidence a successor company, or to make such provision in regard to questions arising under the CL&P Indenture as may be necessary or desirable and not inconsistent with its terms. The CL&P Indenture may also be amended without bondholder consent if the changes do not adversely affect the interests of the holders of any series of CL&P Bonds in any material respect.

The CL&P Indenture also permits the modification, with the consent of holders of 662/3% of the CL&P Bonds affected, of any provision of the CL&P Indenture, except that (a) no such modification may effect a reduction of such percentage unless all bondholders consent, (b) no such modification may effect the creation of a lien equal with or prior to that of the CL&P Indenture unless all bondholders consent, (c) no bondholder who refuses to consent may be deprived of his security and (d) our obligations as to the maturities, payment of principal, interest or premium and other terms of payment may not be modified unless all affected bondholders consent.

The B Provisions would remove the 662/3% consent requirement and permit modifications with the consent of holders of a majority of the CL&P Bonds so affected, but generally retains the

19





Table of Contents

restrictions described in (a) and (d) of the preceding paragraph. Under the B Provisions, the restriction described in (b) of the preceding paragraph would become inapplicable because the B Provisions also would permit the creation of a lien equal with or prior to that of the CL&P Indenture (as described above in the third paragraph under ‘‘Security’’). The B Provisions also generally retains the restriction described in (c) of the preceding paragraph, but would permit, without bondholder consent, modifications that release the lien of the CL&P Indenture on mortgaged property having an aggregate value not greater than 10% of the aggregate value of all mortgaged property at the time the B Provisions become effective.

Security.    The PSNH Indenture constitutes a first mortgage lien (subject to liens permitted by the PSNH Indenture) on substantially all of our property and franchises, including its generating stations and its transmission and distribution facilities, subject to certain customary exceptions. Subject to the provisions of the Federal Bankruptcy Code, the PSNH Indenture also constitutes a lien on after-acquired property in New Hampshire, Maine and Vermont, except real property in Maine and Vermont acquired after the filing of the most recent supplemental indenture. The security afforded by the PSNH Indenture is for the equal and ratable protection of the PSNH Bonds of all series issued under the PSNH Indenture.

Under certain limited circumstances, the lien of the PSNH Indenture on our real property in New Hampshire, personal property located thereon and business revenues generated therefrom could be subordinated to a lien in favor of the State of New Hampshire pursuant to New Hampshire Revised Statutes Annotated 147-B:10-b, as amended, for expenses incurred in containing or removing hazardous waste or materials, and any necessary mitigation of damages with respect to hazardous waste or materials.

Further, the lien of the PSNH Indenture on our real property in Maine could be subordinated to a lien in favor of the State of Maine pursuant to Maine Revised Statutes Annotated, Title 38, Section 1371 for costs of abatement, cleanup or mitigation of hazardous substances.

The PSNH Indenture generally requires us to deposit with the PSNH Bond Trustee all proceeds from the sale or disposition of property except that we may dispose of property having an aggregate cost or fair value, whichever is less, of not more than $5 million in any year without depositing the proceeds thereof with the PSNH Bond Trustee.

Issuance of Additional PSNH Bonds — Basis for Issuance.    We may issue additional PSNH Bonds (in addition to certain refunding bonds and bonds issued against the deposit of an equal amount of cash) under the PSNH Indenture if, after giving effect to such issuance, certain limitations are met.

Additional PSNH Bonds may also be issued (i) to refund other bonds or certain prior lien obligations provided that if PSNH Bonds are to be issued to refund bonds or prior lien obligations more than one year after the maturity of such bonds or prior lien obligations, the PSNH Bonds so issued are subject to the aggregate limitation set forth above (§§ 4.2 and 4.3) and (ii) against the deposit of an equal amount of cash with the PSNH Bond Trustee (§ 4.6).

If cash is deposited with the PSNH Bond Trustee as a basis for the issue of PSNH Bonds, it may be withdrawn from time to time in an amount equal to 662/3% of available bondable property additions or equal to the aggregate principal amount of PSNH Bonds or refundable prior lien obligations that would otherwise be available to be made the basis of the issue of additional PSNH Bonds. Such cash may also be used to purchase or redeem bonds as PSNH may designate. (§ 4.6)

Issuance of Additional PSNH Bonds — Earnings Coverage.    Except for certain refunding bonds, we may not issue additional PSNH Bonds unless our net earnings, as defined and as computed without deducting income taxes or the amortization of the regulatory asset, for 12 consecutive calendar months during the period of 15 consecutive calendar months immediately preceding the first day of the month in which the application of the PSNH Bond Trustee for additional PSNH Bonds is made were at least twice our annual interest requirements. (§ 4.8)

Renewal and Replacement Fund.    On or before May 1 of each year, we will deliver to the PSNH Bond Trustee a maintenance certificate which shall be dated within thirty days of the date of delivery to the PSNH Bond Trustee. In case any maintenance certificate shows a Replacement Deficit, as hereinafter defined, we will, concurrently with the filing of such certificate, satisfy such Replacement Deficit, by depositing cash with the PSNH Bond Trustee, or by depositing with the PSNH Bond Trustee bonds or refundable prior lien obligations which would otherwise be available as a basis for the issue of additional PSNH Bonds or by specifying to the PSNH Bond Trustee bondable property additions. On our application to the PSNH Bond Trustee, any cash so deposited may be used to purchase or redeem first mortgage bonds. ‘‘Replacement Deficit’’ refers to the amount by which the

21





Table of Contents

aggregate amount expended by us for property additions since January 1, 1991 is less than the replacement fund requirement for the same period. The replacement fund requirement is computed on an annual basis and is equal for each year to 2.25% of the average of the amounts carried on our books as of May 16, 1991 for net depreciable property owned by us on such date, plus cumulative gross property additions thereafter which constitute part of the trust estate under the PSNH Indenture (excluding the regulatory asset and any other adjustments made prior to such date) at the beginning and end of the year. (§ 5.5)

Covenants.    The PSNH Indenture includes covenants which, among other things, restrict prior liens, require the maintenance of insurance coverage (subject to certain rights to self-insure) and require the recording and re-recording of the PSNH Indenture. (Article 5)

Withdrawal of Moneys Held by PSNH Bond Trustee.    Any moneys deposited with the PSNH Bond Trustee and any other monies held by the PSNH Bond Trustee as part of the trust estate shall be paid over from time to time by the PSNH Bond Trustee upon our application to or upon the order of our Treasurer or an Assistant Treasurer in an amount equal to 100% of bondable property additions or in an amount equal to the principal amount of PSNH Bonds or refundable prior lien obligations which would otherwise be available as a basis for the issue of additional PSNH Bonds. (§ 8.1)

Any moneys held by the PSNH Bond Trustee as part of the trust estate (other than moneys deposited in a sinking or improvement fund for the benefit of a particular series of PSNH Bonds) shall, at the election and in accordance with our request, be applied by the PSNH Bond Trustee (i) from time to time to the purchase of outstanding PSNH Bonds in the manner provided in the PSNH Indenture or (ii) to the payment at maturity of any PSNH Bonds issued and outstanding under the PSNH Indenture or (iii) in reduction of the amount then required to be deposited by PSNH with the PSNH Bond Trustee in connection with the redemption of PSNH Bonds issued and outstanding under the PSNH Indenture. (§ 8.2)

Events of Default.    The PSNH Indenture provides that the following events will constitute ‘‘events of default’’ thereunder: failure to pay principal; failure for 30 days to pay interest; failure to perform any of the other PSNH Indenture covenants for 90 days after notice to us; default under one or more prior lien obligations aggregating not less than $25 million (other than certain prior lien obligations deposited with the PSNH Bond Trustee); and certain events of bankruptcy, insolvency or receivership. (§ 10.1)

The PSNH Indenture provides that, if an event of default exists, the PSNH Bond Trustee may, and upon the written request of the holders of 25% or more in principal amount of the PSNH Bonds then outstanding, the PSNH Bond Trustee shall, declare the principal of all the PSNH Bonds then outstanding to be immediately due and payable and that upon the occurrence of certain events of bankruptcy, insolvency or receivership, the principal of all the PSNH Bonds then outstanding shall become due and payable without any action by the bondholders or the PSNH Bond Trustee, subject in each case to the right of holders of a majority in principal amount of PSNH Bonds then outstanding to disapprove, rescind or annul such declaration. (§ 10.1)

The PSNH Bond Trustee is required by the Trust Indenture Act of 1939, as amended, to give to the bondholders, by mail, notice of the happening of all defaults known to it within 90 days after the occurrence thereof. However, except in the case of a default resulting from the failure to make any payment of principal of or interest on the PSNH Bonds, or in the payment of any sinking or purchase fund installment, the PSNH Bond Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or responsible officers of the PSNH Bond Trustee in good faith determine that the withholding of such notice is in the interests of the bondholders. The PSNH Bond Trustee is not required to give notice of any default which has been cured or waived.

Modification of the PSNH Indenture.    Without the consent of the bondholders, the PSNH Indenture may be supplemented or amended, among other things, to convey additional. property, to further add to our covenants and agreements, to evidence a successor to us, to correct any

defective or ambiguous provision in the PSNH Indenture, to provide for the issue of PSNH Bonds of any series, to comply with the rules and regulations of any securities exchange on which any of the PSNH Bonds may be listed, to reflect accounting changes as appropriate to conform with generally accepted accounting principles, or to modify, amend, or supplement the PSNH Indenture or any indenture supplemental thereto in such a manner as to permit qualification under the Trust Indenture Act of 1939, as amended. (§ 15.1)

With the consent of the holders of not less than a majority in aggregate principal amount of the PSNH Bonds at the time outstanding (or in case one or more, but less than all, of the series of PSNH Bonds then outstanding would be materially adversely affected, with the consent of not less than a majority in aggregate principal amount of the PSNH Bonds of each series then outstanding which would be materially adversely affected by the action proposed to be taken), we may, from time to time and at any time, enter into an indenture or indentures supplemental to the PSNH Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the indenture or of any supplemental indenture. However, no such supplemental indenture shall operate (i) to permit the extension of the time or times of payment of the principal of, or interest or premium, if any, on any of the PSNH Bonds or the reduction in the principal amount thereof or the rate of interest or the amount of premium thereon or otherwise affect the terms of payment of such principal or interest or premium, if any, on any of the PSNH Bonds, without the consent of the holder of each bond so affected, or (ii) to reduce the aforesaid percentage of PSNH Bonds, the holders of which are required to consent to any such supplemental indenture, without the consent of the holders of all PSNH Bonds outstanding, or (iii) to permit the creation by us of any mortgage or pledge or lien in the nature thereof, ranking prior to or equal with the lien of the PSNH Indenture, and not otherwise permitted under the PSNH Indenture, on any material part of the trust estate without the consent of the holders of all PSNH Bonds outstanding, or (iv) to deprive the holder of any PSNH Bond outstanding of the lien of the PSNH Indenture on any material part of the trust estate without the express consent of the holder of each PSNH Bond affected thereby. (§ 15.2)

Concerning the PSNH Bond Trustee.    The PSNH Bond Trustee under the PSNH Indenture, and affiliates of the PSNH Bond Trustee, are also trustees under other indentures and trust agreements of affiliates of ours. In addition, the PSNH Bond Trustee is a lending party to two revolving credit facilities for Northeast Utilities companies with total commitment amounts under each facility of approximately $52.3 million and $41.8 million.

The WMECO Senior Notes

General.    The following description sets forth certain general terms and provisions of the senior unsecured notes WMECO may issue under the WMECO Indenture (as defined below) (WMECO Notes) to which any prospectus supplement may relate. The description does not purport to be complete and is subject to, and qualified in its entirety by, all of the provisions of the WMECO Note Indenture (as defined below), which is incorporated herein by reference and is an exhibit to the Registration Statement of which this prospectus is a part. The particular terms of the WMECO Notes offered by any prospectus supplement and the extent, if any, to which such general provisions may apply to the WMECO Notes so offered will be described therein. References to section numbers under this caption are references to the section numbers of the WMECO Note Indenture. Capitalized terms not defined herein have the meanings given to them in the WMECO Note Indenture. If there is any inconsistency between the information in this prospectus and the prospectus supplement, you should rely on the information in the prospectus supplement.

The WMECO Notes will be issued under an indenture (the WMECO Note Indenture), between us and The Bank of New York, a New York banking corporation, as trustee (the WMECO Note Trustee) dated as of September 1, 2003, as amended and supplemented.

The WMECO Notes will be our senior unsecured debt securities and will rate equally with all of our other unsecured and unsubordinated debt. There is no requirement under the WMECO Note Indenture that future issues of our debt securities be issued under the WMECO Note Indenture, and we will be free to use other indentures or documentation, containing provisions different from those included in the WMECO Note Indenture or applicable to one or more issues of WMECO Notes, in connection with future issues of such other debt securities.

The WMECO Note Indenture does not limit the aggregate principal amount of the WMECO Notes that may be issued thereunder. The WMECO Note Indenture provides that the WMECO Notes will be issued in one or more series as notes or debentures. The WMECO Notes may be issued at various times and may have differing maturity dates and may bear interest at differing rates. The prospectus supplement applicable to each issue of WMECO Notes will specify:

  the designation and aggregate principal amount of such WMECO Notes;   the date or dates on which such WMECO Notes will mature;   the interest rate or rates, or method of calculation of such rate or rates, on such WMECO Notes, and the date from which such interest shall accrue;   the dates on which such interest will be payable or method by which such dates are to be determined;   the record dates for payments of interest;   any redemption terms;   the period or periods within which, the price or prices at which, and the terms and conditions upon which, such WMECO Notes may be repaid, in whole or in part, at our option;   the place or places, if any, in addition to or in the place of our office or the office of the Senior Note Trustee, where the principal of (and premium, if any) and interest, if any, on such WMECO Notes shall be payable and where notices to WMECO shall be sent; and   other specific terms applicable to such WMECO Notes. (Section 301)

Unless otherwise indicated in the applicable prospectus supplement, the WMECO Notes will be denominated in United States currency in minimum denominations of $1,000 and integral multiples thereof. (Section 301)

24





Table of Contents

Unless otherwise indicated in the applicable prospectus supplement or as below described under ‘‘Limitation on Liens’’ and ‘‘Sale and Leaseback Transactions’’, there are no provisions in the WMECO Note Indenture or the WMECO Notes that require us to redeem, or permit the holders of the WMECO Notes to cause a redemption of, the WMECO Notes or that otherwise protect the holders of the WMECO Notes in the event that we incur substantial additional indebtedness, whether or not in connection with a change in control of us.

Our ability to meet our obligations under the WMECO Notes is dependent on our earnings and cash flows. Unless otherwise specified in a prospectus supplement, the Supplemental Indentures will not limit the amount of indebtedness or preferred stock we may issue.

Registration, Transfer, Exchange and Form.    WMECO Notes of any series may be exchanged for other WMECO Notes of the same series of any authorized denominations and of a like aggregate principal amount and tenor. (Section 305)

Unless otherwise indicated in the applicable prospectus supplement, WMECO Notes may be presented for registration of transfer (duly endorsed or accompanied by a duly executed written instrument of transfer) at the office or agency maintained for such purpose with respect to any series of WMECO Notes and referred to in the applicable prospectus supplement, without service charge and upon payment of any taxes and other governmental charges as described in the WMECO Note Indenture. (Section 305)

In the event of any redemption of WMECO Notes of any series, we will not be required to exchange, or register the transfer of, any WMECO Notes of such series selected, called or being called for redemption except, in the case of any WMECO Note to be redeemed in part, the portion thereof not to be so redeemed. (Section 305)

Paying Agents.    We will maintain an office or agency where WMECO Notes may be presented or surrendered for payment. We will give prompt written notice to the WMECO Note Trustee of the location, and any change in the location, of such office or agency. If at any time we shall fail to maintain any such required office or agency or shall fail to furnish the WMECO Note Trustee with the address thereof, such presentations and surrenders may be made or served at the corporate trust office of the WMECO Note Trustee, and, in such event, the WMECO Note Trustee shall act as our agent to receive all such presentations and surrenders. (Section 1002)

All monies paid by us to a paying agent for the payment of principal of, interest or premium, if any, on any WMECO Note which remains unclaimed at the end of two years after any such principal, interest or premium shall have become due and payable will be repaid to us at our request and the Holder of such WMECO Note will thereafter look only to us for payment thereof as an unsecured general creditor. (Section 1003)

Consolidation, Merger, Conveyance, Sale or Transfer.    Nothing contained in the WMECO Note Indenture prevents us from consolidating with or merging into another corporation or conveying, selling or otherwise transferring our properties and assets substantially as an entirety to any Person, provided that:

  the corporation formed by such consolidation or into which we are merged or the Person which acquires by conveyance, sale or transfer our properties and assets substantially as an entirety is a corporation organized and existing under the laws of the United States of America, any State thereof or the District of Columbia and expressly assumes by an indenture supplemental thereto, executed and delivered to the Senior Note Trustee, in form satisfactory to the WMECO Note Trustee, the due and punctual payment of the principal of (and premium, if any) and interest, if any, on all the WMECO Notes and the performance of every covenant of the WMECO Note Indenture on our part to be performed or observed; and   immediately after giving effect to the transaction, no Event of Default, and no event which, after notice or lapse of time or both, would become an Event of Default, shall have occurred and be continuing.

25





Table of Contents

We shall also be required to deliver to the WMECO Note Trustee certificates and opinions stating that such consolidation, merger, conveyance, sale or transfer comply with the WMECO Note Indenture and all relevant conditions precedent have been satisfied. (Section 801)

Limitation on Liens.    Nothing contained in the WMECO Note Indenture or in the WMECO Notes in any way restricts or prevents us from incurring any indebtedness; provided that if this covenant is made applicable to the WMECO Notes of any particular series, we will not issue, assume or guarantee (including any contingent obligation to purchase) or permit to exist any notes, bonds, debentures or other evidences of indebtedness for money borrowed (Debt) secured by a mortgage, lien, pledge, security interest or other encumbrance (Lien) upon any of our property, without effectively providing that the outstanding WMECO Notes of such series (together with, if we so determine, any other indebtedness or obligation then existing or thereafter created ranking equally with the WMECO Notes of such series) shall be secured equally and ratably with (or prior to) such Debt so long as such Debt shall be so secured (provided that for purposes of providing such equal and ratable security, the principal amount of outstanding WMECO Notes of any series will be such portion of the principal amount as may be specified in the terms of such series). This restriction will not, however, apply to:

  Liens in existence on the date of the original issue of the WMECO Notes to which this restriction is made applicable;   Liens created solely for the purpose of securing Debt incurred to finance, refinance or refund the purchase price or cost (including the cost of construction) of property acquired after the date of the Senior Note Indenture (by purchase, construction or otherwise), or Liens in favor of guarantors of obligations or Debt representing, or incurred to finance, refinance or refund, such purchase price or cost, provided that no such Lien shall extend to or cover any property other than the property so acquired and improvements thereon and provided further that such Liens are created no later than 24 months after the purchase or construction;   Liens on any property or assets acquired from a corporation which is merged with or into us, which Liens are not created as a result of or in connection with or in anticipation of any such merger (unless such Liens were created to secure or provide for the payment of any part of the purchase price of such corporation);   Any Lien on any property or assets existing at the time of acquisition thereof and which is not created as a result of or in connection with or in anticipation of such acquisition (unless such Lien was created to secure or provide for the payment of any part of the purchase price of such property or assets); or   Any extension, renewal or replacement of any Lien referred to in the foregoing clauses, provided that the principal amount of Debt so secured thereby shall not exceed the principal amount of Debt so secured at the time of such extension, renewal or replacement, and that such extension, renewal or replacement Lien shall be limited to all or part of substantially the same property which secured the Lien extended, renewed or replaced (plus improvements on such property).

Notwithstanding the foregoing, we may issue or assume Debt secured by Liens which would otherwise be subject to the foregoing restrictions in an aggregate principal amount which does not at the time of issuance or assumption exceed 10% of the principal amount of the WMECO Notes then outstanding. (Section 1007)

Table of Contents

Sale and Leaseback Transactions.    If this covenant is made applicable to the WMECO Notes of any series, we will not enter into any Sale and Leaseback Transaction unless either:

  we would be entitled, pursuant to the ‘‘Limitation on Liens’’ covenant above, to create Debt secured by a Lien on the property to be leased back in an amount equal to the Attributable Value of such Sale and Leaseback Transaction without the WMECO Notes being effectively secured equally and ratably with (or prior to) that Debt; or   we, within 270 days after the sale or transfer of the relevant assets shall have been made, apply, in the case of a sale or transfer for cash, an amount equal to the net proceeds from the sale or, in the case of a sale or transfer otherwise than for cash, an amount equal to the fair market value of the property so leased (as determined by any two of our Directors) to:   the retirement of our long-term indebtedness ranking prior to or on a parity with the WMECO Notes or   the investment in any property used in the ordinary course of our business.

‘‘Attributable Value’’ means, as to any particular lease under which we are at any time liable as lessee and at any date as of which the amount thereof is to be determined, the amount equal to the greater of (i) the net proceeds from the sale or transfer of the property leased pursuant to the Sale and Leaseback Transaction or (ii) the net book value of the property, as determined by us in accordance with generally accepted accounting principles at the time of entering into the Sale and Leaseback Transaction, in either case multiplied by a fraction, the numerator of which shall be equal to the number of full years of the term of the lease that is part of the Sale and Leaseback Transaction remaining at the time of determination and the denominator of which shall be equal to the number of full years of the term, without regard, in any case, to any renewal or extension options contained in the lease.

‘‘Sale and Leaseback Transaction’’ means any transaction or series of related transactions relating to property now owned or hereafter acquired by us whereby we transfer the property to a person and we lease it from that person for a period, including renewals, in excess of 36 months. (Section 1012)

Modification of the WMECO Note Indenture.    The WMECO Note Indenture contains provisions permitting us and the WMECO Note Trustee, with the consent of the holders of a majority in principal amount of the outstanding WMECO Notes, of all series affected by the modification (voting as one class), to modify the WMECO Note Indenture or any supplemental indenture or the rights of the holders of the WMECO Notes of such series; provided that no such modification shall without the consent of the holders of each outstanding WMECO Note affected thereby:

  change the date upon which the principal of or the interest on any WMECO Note is due and payable;   reduce the principal amount thereof or the rate of interest thereon or any premium payable upon the redemption thereof;   change any place of payment where, or the currency in which, any WMECO Note or any premium or the interest thereon is ayable;   impair the right to institute suit for the enforcement of any payment on or after the date such payment is due (or, in the case of redemption, on or after the date fixed for such redemption);   reduce the aforesaid percentage of WMECO Notes, the consent of the holders of which is required for any modification of the applicable supplemental indenture or for waiver by the holders of certain of their rights; or   modify certain provisions of the WMECO Note Indenture. (Section 902)

The WMECO Note Indenture also contains provisions permitting us and the WMECO Note Trustee to amend the WMECO Note Indenture in certain circumstances without the consent of the holders of any WMECO Notes to evidence the succession of another person to us, the replacement of

27





Table of Contents

the WMECO Note Trustee and for certain other purposes, including to cure any ambiguity or defect, or correct any inconsistency, in the WMECO Note Indenture, or to add or change any other provisions with respect to matters or questions arising under the WMECO Note Indenture or the WMECO Notes, provided such changes or additions shall not adversely affect the interests of the holders of any series of the WMECO Notes in any material respect, or involve a change requiring the consent of the holders of the WMECO Notes described in the preceding paragraph. (Section 901)

Events of Default.    An Event of Default with respect to the WMECO Notes is defined in the WMECO Note Indenture as being:

  failure to pay any interest on the WMECO Notes and continuance of such failure for 30 days;   failure to pay the principal (or premium, if any), including the payment of principal (or premium, if any) when due pursuant to any redemption provision of the WMECO Notes and continuance of such failure for three days;   failure to pay any sinking fund installment, if any, pursuant to the terms of the WMECO Notes, and continuance of such failure for a period of three days;   default in the performance, or breach, of any covenant or warranty of ours in the WMECO Note Indenture (other than certain covenants or warranties a default in whose performance or whose breach is specifically dealt with elsewhere in the WMECO Note Indenture or which has been expressly included in the WMECO Note Indenture solely for the benefit of any series of WMECO Notes other than that series) and continuance of such default or breach for a period of 90 days after written notice is given to us by the WMECO Note Trustee or to us and the WMECO Note Trustee by the holders of 33% or more in aggregate principal amount of the outstanding WMECO Notes; and   certain events of bankruptcy, insolvency, reorganization, receivership or liquidation involving us. (Section 501)

We will be required to file with the WMECO Note Trustee annually an officers’ certificate as to the existence or absence of default in performance of certain covenants in the WMECO Note Indenture. (Section 1008) The WMECO Note Indenture provides that the WMECO Note Trustee may withhold notice to the holders of the WMECO Notes of any default (except in payment of principal of (or premium, if any), or interest, if any, on, the WMECO Notes or in the payment of any sinking fund installment with respect to the WMECO Notes) if the WMECO Note Trustee in good faith determines that it is in the interest of the holders of the WMECO Notes to do so. (Section 602) The WMECO Note Indenture provides that, if an Event of Default due to the default in payment of principal of (or premium, if any) or interest on the WMECO Notes or in the payment of any sinking fund installment with respect to the WMECO Notes, or due to the default in the performance or breach of any covenant or warranty in the WMECO Note Indenture by us shall have happened and be continuing, either the WMECO Note Trustee or the holders of 33% or more in aggregate principal amount of the outstanding WMECO Notes may declare the principal amount of all the WMECO Notes to be due and payable immediately, but if we shall cure all defaults and certain other conditions are met, such declaration may be annulled and past defaults may be waived by the holders of a majority in aggregate principal amount of the WMECO Notes. If an Event of Default due to certain events of bankruptcy, insolvency or reorganization has occurred and is continuing, the principal amount of all the WMECO Notes shall be immediately due and payable, without any act of either the WMECO Note Trustee or the holders. (Sections 502 and 513)

Subject to the provisions of the WMECO Note Indenture relating to the duties of the WMECO Note Trustee, the WMECO Note Trustee will be under no obligation to exercise any of its rights or powers under the WMECO Note Indenture at the request or direction of any of the holders of the WMECO Notes, unless such holders shall have offered to the WMECO Note Trustee reasonable indemnity. (Section 603)

Subject to such provision for indemnification, the holders of a majority in principal amount of the WMECO Notes will have the right to direct the time, method and place of conducting any proceeding

28





Table of Contents

for any remedy available to the WMECO Note Trustee, or exercising any trust or power conferred on the WMECO Note Trustee with respect to the WMECO Notes, provided, however, that if an Event of Default shall have occurred and be continuing with respect to less than all of the series of WMECO Notes, the holders of a majority in aggregate principal amount of the WMECO Notes of all such series, considered as one class, shall have the right to make such direction, and provided that the WMECO Note Trustee shall have the right to decline to follow any such direction if the WMECO Note Trustee shall determine that the action so directed conflicts with any law or the provisions of the WMECO Note Indenture or if the WMECO Note Trustee shall determine that such action would subject the WMECO Note Trustee to personal liability or expense for which reasonable indemnity has not been provided. (Section 512)

Defeasance.    We, at our option, (a) will be Discharged from any and all obligations in respect of the WMECO Notes (except for certain obligations to register the transfer or exchange of WMECO Notes, replace destroyed, stolen, lost or mutilated WMECO Notes, maintain paying agencies and hold moneys for payment in trust) or (b) need not comply with certain covenants of the WMECO Note Indenture described under ‘‘— Consolidation, Merger, Conveyance, Sale or Transfer’’ and ‘‘— Limitation of Liens’’ or to certain covenants relating to corporate existence and maintenance of properties and insurance, in each case, if:

(Sections 403 and 1009)

Discharged means, with respect to the WMECO Notes of any series, the discharge of the entire indebtedness represented by, and obligations of ours under, the WMECO Notes of such series and in the satisfaction of all the obligations of ours under the WMECO Note Indenture relating to the WMECO Notes of such series, except:

(Section 101)

Resignation or Removal of Senior Note Trustee.    The WMECO Note Trustee may resign at any time upon written notice to us, and such resignation will take effect immediately upon the appointment of a successor WMECO Note Trustee. (Sections 610 and 611)

The WMECO Note Trustee may be removed at any time by an instrument or concurrent instruments in writing delivered to the WMECO Note Trustee and us and signed by the holders, or their attorneys-in-fact, of at least a majority in principal amount of the then outstanding WMECO Notes. In addition, under certain circumstances, we may remove the WMECO Note Trustee upon notice to the Holder of each WMECO Note outstanding and the WMECO Note Trustee, and appointment of a successor WMECO Note Trustee. (Section 610)

No Recourse Against Others.    The WMECO Note Indenture provides that no recourse for the payment of the principal of or any premium or interest on any WMECO Note, or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of ours, contained in the WMECO Note Indenture or in any supplemental indenture, or in any WMECO Note, or because of the creation of any indebtedness represented thereby, will be had against any trustee, incorporator, stockholder, officer or director, as such, past, present or future, of ours or any successor corporation, either directly or through us or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that all such liability is expressly waived and released as a condition of, and in consideration for, the execution of the WMECO Note Indenture and the issuance of the WMECO Notes. (Section 114) Such waiver may not be effective to waive liabilities under the Federal securities laws and we understand that it is the view of the Commission that such a waiver is against public policy.

Concerning the Senior Note Trustee.    The WMECO Note Trustee under the WMECO Indenture, and affiliates of the WMECO Note Trustee, are also trustees under other indentures and trust agreements of affiliates of ours. In addition, the WMECO Note Trustee is a lending party to two of our system revolving credit facilities with total commitment amounts under each facility of approximately $34.9 million and $67.7 million.

BOOK ENTRY SYSTEM

The Depository Trust Company (DTC) will act as securities depository for all the securities being registered by this Registration Statement (the Securities). The Securities will be issued as fully-registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. One fully-registered Security certificate (Global Certificate) will be issued for each issue of the Securities, each in the aggregate principal amount of such issue, and will be deposited with DTC. If, however, the aggregate principal amount of any issue exceeds $500 million, one certificate will be issued with respect to each

$500 million of principal amount and an additional certificate will be issued with respect to any remaining principal amount of such issue. Certificated securities will not be exchangeable for Global Certificates and, except under the circumstances described below, the Global Certificates will not be exchangeable for certificated securities.

DTC, the world’s largest depository, is a limited-purpose trust company organized under the New York Banking Law, a ‘‘banking organization’’ within the meaning of the New York Banking Law, a member of the Federal Reserve System, a ‘‘clearing corporation’’ within the meaning of the New York Uniform Commercial Code, and a ‘‘clearing agency’’ registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934. DTC holds and provides asset servicing for over 2.2 million issues of U.S. and non-US. equity, corporate and municipal debt issues, and money market instruments from over 100 countries that DTC’s participants (Direct Participants) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-US. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (DTCC). DTCC, in turn, is owned by a number of Direct Participants of DTC and Members of the National Securities Clearing Corporation, Fixed Income Clearing Corporation, and Emerging Markets Clearing Corporation (NSCC, FICC, and EMCC, also subsidiaries of DTCC), as well as by the New York Stock Exchange, Inc., the American Stock Exchange LLC, and the National Association of Securities Dealers, Inc. Access to the DTC system is also available to others such as both U.S. and non-US. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (Indirect Participants). DTC has Standard & Poor’s highest rating: AAA. The DTC Rules applicable to its Participants are on file with the Securities and Exchange Commission. More information about DTC can be found at www.dtcc.com and www.dtc.org.

Purchases of Securities under the DTC system must be made by or through Direct Participants, which will receive a credit for the Securities on DTC’s records. The ownership interest of each actual purchaser of each Security (Beneficial Owner) is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the Securities are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in Securities, except in the event that use of the book-entry system for the Securities is discontinued.

To facilitate subsequent transfers, all Securities deposited by Direct Participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co. or such other name as may be requested by an authorized representative of DTC. The deposit of Securities with DTC and their registration in the name of Cede & Co. or such other nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Securities; DTC’s records reflect only the identity of the Direct Participants to whose accounts such Securities are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time. Beneficial Owners of Securities may wish to take certain steps to augment transmission to them of notices of significant events with respect to the Securities, such as redemptions, tenders, defaults, and proposed amendments to the security documents. For example, Beneficial Owners of Securities may wish to ascertain that the nominee

holding the Securities for their benefit has agreed to obtain and transmit notices to Beneficial Owners, in the alternative, Beneficial Owners may wish to provide their names and addresses to the registrar and request that copies of the notices be provided directly to them.

Redemption notices shall be sent to DTC. If less than all of the Securities within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.

Neither DTC nor Cede & Co. (nor such other DTC nominee) will consent or vote with respect to the Securities unless authorized by a Direct Participant in accordance with DTC’s Procedures. Under its usual procedures, DTC mails an Omnibus Proxy to the securities issuer (Issuer) as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants to whose accounts the Securities are credited on the record date (identified in a listing attached to the Omnibus Proxy).

Redemption proceeds, distributions, and dividend payments on the Securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct Participants’ accounts, upon DTC’s receipt of funds and corresponding detail information from Issuer or Agent on payable date in accordance with their respective holdings shown on DTC’s records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in ‘‘street name,’’ and will be the responsibility of such Participant and not of DTC nor its nominee, Agent, or Issuer, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds, distributions, and dividend payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of Issuer or Agent, disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect Participants.

A Beneficial Owner shall give notice to elect to have its Securities purchased or tendered, through its Participant, to Tender/Remarketing Agent, and shall effect delivery of such Securities by causing the Direct Participant to transfer the Participant’s interest in the Securities, on DTC’s records, to Tender/Remarketing Agent. The requirement for physical delivery of Securities in connection with an optional tender or a mandatory purchase will be deemed satisfied when the ownership rights in the Securities are transferred by Direct Participants on DTC’s records and followed by a book-entry credit of tendered Securities to Tender/Remarketing Agent’s DTC account.

DTC may discontinue providing its services as securities depository with respect to the Securities at any time by giving reasonable notice to Issuer or Agent. Under such circumstances, in the event that a successor securities depository is not obtained, Security certificates are required to be printed and delivered.

We may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository). In that event, Security certificates will be printed and delivered to DTC.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.

LEGAL OPINIONS

Unless otherwise noted in the applicable prospectus supplement, legal opinions relating to the validity of the securities will be given by Jeffrey C. Miller, Assistant General Counsel of Northeast Utilities Service Company, a service company affiliate of ours.
